There's a parenthesis to much after NU.

Thank you,
I fixed all paranthesis problems and simulation went much more further,
but I`ve got an error anyway:
www.dropbox.com/s/4lxhzv4w7r3cb27/rot3_case2.mess?dl=0
Is it problem with group?
I defined just one group "fix" (it is a surface of hub hole).

LIRE_MAILAGE doesn't find any groups. Make sure you defined it properly in the mesh and exported it correctly.

Thank you,
yes, my mistake, I created group inside geometry but I have to do this inside mesh.
Could you please cuggest what exactly mesh group for rotation should look like?
Is it just axis (edge group)? or it should be defined in more complex (points, edges, surfaces, volumes) way?
Regards.

Rotation is defined for the entire model - or perhaps individual parts, I can't remember - so you should define how the wheel is fixed.
Fixing faces inside the inner hole / where the axel would go through would be a good idea.
A face group can only be fixed in DX, DY, DZ and NOT DRX, DRY, DRZ just in case you where going to try that >_o

Thank you,
I set "fix" group inside mesh (surface inside hub) and "rot" group (entire wheel) but still have error.
www.dropbox.com/s/dgpdm9ha8bzzpqm/rot6.comm?dl=0
www.dropbox.com/s/lja198whwrvxdzc/rot6_1.mess?dl=0
Looks like something is still missing or uncorectly defined in command file. May be I have to add also rotation axis or it is already done with this: AXE=(0,0,1,)?
Please help me to make this wheel finally rotate.
Regards.
