Application of a torque as a boundary condition

Hello,

As the subject indicates, I would like to be able to apply a torque to a boundary of a body, but can't work out a way of doing such a thing with elmer.

Is it possible?

Thanks,
John

Displacements in Elastic solver when calculating eigenmodes

Hi all, I am currently using the elasticity solver to calculate the eigenmodes of a cantilevered beam. The Eigenvalues that are produced are reasonable. The mode shapes look the correct shape, but the didplacements given are rather large (see the attached image) given that the beam length is 0.00035...

Re: Solver unable to find FlowSolve.dll

Aha! that has sorted it Thank You. I should probably have noticed the library version part of the Solver Log.

Solver unable to find FlowSolve.dll

Hi, I have upgraded to Elmer7, using the windows binary on xp. I have been using a previous version of Elmer successfully for some time. However, I now have the following problem described in the Solver Log: ELMER SOLVER (v 7.0) STARTED AT: 2012/06/07 13:38:16 MAIN: MAIN: ===========================...

Re: Multiple isosurfaces with opacity

Peter, thankyou for your reply-I'll have a play with paraview.

Is there a reason that the above image looks so bad? some limitation on filesize or somesuch?

Multiple isosurfaces with opacity

Howdy, I would like to show my results (elmer/N-S eqn) using more than one isosurface. Each isosurface with an opacity less than 100%such that the one behind it can be seen. However, this is the result: two_isosurface_opacity.png Obviously that is not useable, is there any way to improve the quality...

Seems that we have solved the problem-it was to do with how the system was handling the memory and shifting it around during calculations...

Re: Relaxation factor

Thanks for your reply!

The point you make with respect to the solution converging in the end is a good one-one that I had not really thought about.
