Hey guyz,

I got the following errors when I tried to compile (wmake) a viscosity model. Everything was fine before with the same change. I don`t really know why I got these errors now:

incompressible]$ wmake

I would be very grateful if anyone can lead me to the source of the error.

Thanks alot,

Probably you want to build a library, not an executable. Use 'wmake libso' to build a library. This is not a bug.

I compiled the new viscosity model with wmake and I used to compile it with wmake every time I changed it. This time I only changed a constant value in it and got the above-mentioned error using wmake! I don`t know what is the reason...

[ICL]

I typed wmake in src/transportModels/incompressible by the way. As I mentioned it was fine using wmake for that before.

[ICL]

First of all, that was not a bug ( Sorry for that)
Use of wmake is possible for executable files such as Solvers. There is a library specified to transportmodels/incompressible and that should be updated using wmake libso incompressible in src/transportmodels directory.

Hi foamers,

I'am working with simpleFoam, and I want to implement a new Herschel-Bulkley model. I have already done all the major steps and modifications required.

Now when I try to execute the command "./Allwmake" in "src/transportModels/", I got the message depicted in the attachment. And even when I use the command "wmake libso incompressible" suggested on this thread, I still have this message. Does anybody know what it may be linked to?

I hope that you will find a couple of minutes to give me a reply. Any contribution will be well aprreciated.

Thanks in advance for your time, and have a nice week.

Regards.

My French is a little rusty, but a few seconds are enough to find the answer:
It says "impossible to create the repository ... permission denied".
In other words, you do not have writing rights in that directory, which makes a lot of sense as it is the "/opt" directory.

You need to either compile using the super-user account [you probably do not want to do this, especially as there is no reason to modify the original OpenFoam source code], or you should compile your modified code in a directory in which you have writing rights. I usually compile my own modifications in ${FOAM_RUN}/../applications or ${FOAM_RUN}/../libraries.
It'd be a good idea to put your executable in $FOAM_USER_APPBIN, instead $FOAM_APPBIN, as it is a user modification.

Good morning Sir,

Thank you very much for your advices, I will take them into account.

Regards.
