Transfer Displacement results from one mesh to another
Transfer Displacement results from one mesh to another
(OP)
Hello Experts,
I need to transfer displacement results from fine mesh to coarse mesh. Also the vice-versa is also needed - coarse to fine.
The transfer of results should be very much close to the actual simulation results.
Thanks,

2) rerun the model ? ... why would you want to copy a coarse mesh displacement onto a fine mesh ?

RE: Transfer Displacement results from one mesh to another
If I understand it correct, in model 1 the displacement is a result while in model 2 it can be seen as a "load"?
If you just make sure that the node numbers in the models are consistent is some way, it should not be to difficult. What I mean by the "consistent" numbers is that node 1 should have the same location in both models so the displacement field becomes the same in both models.
In Femap you should be able to import the results from model 1 into model 2 and then create "Load from results". And I doubt that is a unique feature in Femap. Sounds like you may be playing with the concept of a multigrid solver.
What is the application (if you can share)?

@rb1957, I need to do this displacement transfer for Fine Hex8 to Coarse Hex8. Will Linear Interpolation work fine ?
@ThomasH, Actually I need to write a program in C++ to do this transfer from one mesh to another. Is there any algorithm available ?
RE: Transfer Displacement results from one mesh to another
So you want to create new data as well. Take a look at how a mass matrix handles data, that might do the trick. A linear interpolation might work depending on how accurate you want to be and what the deformation looks like.

2) if HEX8 is a linear element then linear interpolation is reasonable. if 2nd order then parabolic interpolation would be better. maybe you need to create a deformed surface that matches the coarse grid deflections ?
