Hi everyone!

I have actually 2 questions:

1.First of all I would like to know I could constrain the rotation on the pointDisplacement file. How do I block the rotation on the z-axis?

2.I've meshed a boat in four different patches (for better detailing), but I would like to work with them as if they were only one patch! (for giving the the properties on the 0 file: mass, moment of inertia...). How do I do it?

Thanks!

Hi,

I can only answer your 2nd question: use createPatch to create a new patch from your four existing patches....

Details: https://github.com/OpenFOAM/OpenFOAM...reatePatchDict

Cheers,
Antimony

Hi Antimony, thanks for the answer!

Your answer helped, but now I've got a new problem :P
I used createPatch, and it created the patch in time 0.01.
I've copied the polyMesh folder from folder "0.01" to folder "constant", so I would have the patch for time 0 too.
But when I run setFields it shows this error message

Quote:
Create time

Create mesh for time = 0

Reading setFieldsDict



--> FOAM FATAL IO ERROR:
"ill defined primitiveEntry starting at keyword 'defaultFieldValues' on line 19 and ending at line 71"

file: /home/rafael/OpenFOAM/teste/system/setFieldsDict at line 71.

From function primitiveEntry::readEntry(const dictionary&, Istream&)
in file lnInclude/IOerror.C at line 132.

FOAM exiting
Any ideas??

EDIT : It worked ! Just needed to edit the setFields file.

Now I just need to know how to limit the rotation in the z-axis!! Anyone knows?
