Mmm, allright. It seems that all your development sources work for you, so I'll have to find the solution in my own version (which has to be the same as yours, but apparently it isn't).

I just compiled your latest version and tried to run icoDyMFoam on the tutorial movingCone, without success. All other version worked.

Since this problem concerns the standard tutorial passing my case is not very usefull.

Regards, Frank

[hjasak]

Just as a proof: no changes no modifications, all checking switched on. I have tried both the debug and optimised version and the log file is below.

Could you please investigate further why your compilation does not work: dump a core, produce a trace-back, run it in gdb, whatever. (I get a bit upset when people claim there are bugs in my code and I cannot reproduce them - I want to get to the bottom of this because claiming that OpenFOAM does not work when in fact it does isn't too good for its reputation).

There is no core dump, no errors and results all look fine. If you are running linux and wish to try my pre-compiled version, I will upload it for you.

I recently compiled Hrv's code (on an AMD64 under RHEL v3), and it runs without any problems ... What version of gcc are you using? What platform did you compile on?

[lr103476]

I am using gcc version 4.1.1 on a single core Intel processor running RedHat EL4 (kernel version = 2.6.9-11).

Prof Hrvoje Jasak, I do not claim that there are bugs in your code. On the contrary, learning more about the code, I am getting more and more exciting how well things are programmed, how well things work and the vast capabilities of the code.

All that I want is to figure out why my compiled version shows some problems. Moving to newer versions of gcc, OF sources and paraview causes me some problems at this moment. I am not very familiar with core dumps, trace-back and gdb, but tomorrow I will give these things a try. If it is no much work, could you please upload your precompiled version, just to test.

Regards, Frank

[hjasak]

Hi Frank,

Don't worry about it - I am just trying to find out if there are bugs or some problems I haven't see before. Here are two ways to produce a core dump and traceback on linux.

1) from a core file. Type

unlimit

or

limit coredumpsize unlimited

Run the code. This should crash and produce a core file (probably quite large) in the current directory. Once you've got the core do the following

gdb icoDyMFoam core

(note that the name of the core file may have some numbers attached - just use the complete file name). When you get the prompt, type:

where

The stuff that comes up on the screen is a cure trace-back - this is what I need.

2) Running from gdb. Do

gdb icoDyMFoam

Wait until you get the prompt. The do (r is for Run):

r <root> <case>

The effect should be similar to above, but without creating the core file. Once you get the prompt back, type:

where

and send me the trace-back.

I have uploaded a pre-compiled version on:

http://powerlab.fsb.hr/ped/kturbo/OpenFOAM/release/

Enjoy,

Hrv

[lr103476]

Again I have some problems concerning the recompilation of the development sources. Let me give an overview:

==================================
Machine 1: Red Hat Enterprise 4, gcc 4.1.1:

1) compiling prof Jasak's sources (11-09-2006) -> segmentation fault when using icoDyMFoam on movingCone tutorial.

2) compiling prof Jasak's sources (11-09-2006) with DEBUGGING enabled -> icoDyMFoam on movingCone tutorial works (so no core dump since it works:-S) but needs thousands of iterations, strange!

3) using precompiled version of prof Jasak's sources (11-09-2006) -> segmentation fault when using icoDyMFoam on movingCone tutorial.

==================================
Machine 2: OpenSuse 10, gcc 4.1.0:

1) compiling prof Jasak's sources (11-09-2006) -> segmentation fault when using all solvers

2) using precompiled version of prof Jasak's sources (11-09-2006) -> icoDyMFoam on movingCone tutorial works perfectly!

So only the precompiled version works on my home machine, which is not that fast. I want to use my RHEL4 machine. Do I miss some extra libraries?

Regards, Frank

[hjasak]

Sounds nasty - are you picking up the wrong compiler of libstdc++?

I have to say I'm happy you can now see that I was telling the truth when I said "it works for me" :-)

I really don't know how to help further - please feel free to ask specific questions if appropriate.

Hrv

[lr103476]

On my 2 machines different libstdc++ versions are natively installed, when I use rpm -q.... But I thought that this libstdc++ is in the /OpenFOAM/linux/gcc-4.1.1/lib So that one is supposed to be used.

Machine 1: RHEL4
lraspasik:/home/frankl > rpm -q libstdc++
libstdc++-3.4.3-22.1

Machine 2: OpenSUSE 10
mithril:/home/frankl> rpm -q libstdc++
libstdc++-4.0.2_20050901-3

In both cases the foamInstallationTest shows no errors.

Frank

[lr103476]

It seems that all the other solvers are working succesfully on the tutorials.

Is there a specific difference between icoDyMFoam and the other solvers which could cause some compiler related issues? On the other hand, icoDyMFoam works perfectly on the mixer2D tutorial. So a major difference between mixer2D and movingCone could also play a role.

Summarising: it appears that there are compiler and platform dependent pieces of source code present in icoDyMFoam only.

Frank

[mattijs]

icoDymFoam uses the dlopen functionality (loads a .so library at runtime). Possibly your version of os and libraries has problems with it.

Also you get the warning

library "libtetDecompositionMotionSolver.so" did not introduce any new solvers

Maybe there is a problem with loading it twice?

[lr103476]

It is even getting stranger. I've put an exact copy of the precompiled sources, OpenFOAM-1.3 and /linux (11-09-2006) on my network account and icoDyMFoam and everything else works beautifully:-S

So, I've got two exact versions running on the same machine (!!!), but at different locations. Each uses the same versions of gcc (4.1.0) from /OpenFOAM-1.3/linux.
The one from the network location works, the other local version doesn't. Strange!!

At both locations I checked: ldd `which icoDyMFoam`:

Anymore ideas?

here another riddle:

*icoDyMFoam works when installed on the network and run from the network drive on my RHEL4 machine.
*icoDyMFoam fails when installed on the network and run from the local drive on my RHEL4 machine.

In both cases all the links are pointing towards the OpenFOAM en linux dirs on the network drive.

At least this gives me the good feeling that it
will work on our cluster, but I am not able to use my local harddrive while running.

It works using a different user account on my local disk!!! Very strange, but it probably has something to do with my user id settings......but I copied my .bashrc to the new user....strange:-S

Anyway, this is no major problem anymore, and I can resume developing new stuff instead of trying to solve these strange windows-like problems. I bet the new versions will work again using my ordinary user account :-S

Dear Prof Hrvoje Jasak and Framk Bos

I am trying to solve oscillating cylinder in a channel using icoDyMFoam with oscillatingFixedVlaue boundary.

But I have the same problem as Foank Bos had before.

Could you tell me how to fix the problem.
If I need the prof. jasak precompiled OpenFoam,
Could some tell me how to get the code?


Thank you

Dear Prof Jasak

When I run your case "oscillatingCavityMotion"
I have a same problem as Frank Bos
" NO motions are solved"

Please tell me How to fix the problem.
if I need your code, Please tell me How to get is?

Thank you

Hi Pius,

Using the development code of OpenFOAM v1.3 of prof. Jasak (from 11 sept 2006) my problems of "no motion" were solved. I think that he solved some wall BC related problems, which appeared in the current release of OpenFOAM 1.3.

I still have some unknown user profile related problems using that OF version, but creating a new user for OF calculation also solved that problem.

I dont know what the best, either prof Jasak has to provide you his latest sources (I dont know if he still got the version I am using now) or I have to put my working version (precompiled) on my site.

Prof Jasak, do you mind if I share your code? It is still GPL, right?

Regards, Frank

Allright, Pius,

You can take the precompiled development code from my site: www.aero.lr.tudelft.nl/~frank

Hi all,

i am using OF-1.5.
I want to move a rotating cylinder on a circular path in a fluid bordered
by a fix cylinder...

I modded tutorial case movingCone (icoDyMFoam) with type angularOscillatingDisplacement
for movingWall (rotating inner cylinder) in pointMotionU.

The start looks nice...but soon the gridlines coil round the rotating inner cylinder...
(1)Is there any possibility to change this mesh behavior?

(2)Or should i try simpleSRFFoam like in mixer-tutorial? But how to realize the circular path?

I would be grateful for any hints.

Andy

hi...

solved the problem...

- used setBoundary to put a velocity profile on the inner cylinder which will not move anymore
[please change binary to ascii in controlDict/write if you build your case from movingCone- tutorial!!]

- changed oscillatingDisplacement.C and .H (compile with Allwmake in /OF-1.5/src...first time compiling takes a little time ;)) to create a circular path for the outer cylinder

-axis of both cylinders should differ

so no more mesh-problems occurs

perhaps someone has a smarter way to move something on a circular path...i didn`t
find one...

Andy
