[Libmesh-users] Really weird errors. any ideas what I could be doing wrong?

2013-07-04 Thread Subramanya Sadasiva
I am implementing a multiphysics solver with multiple steps of solution.. The first step .. solution of a poisson equation to get electrical potential distribution works fine. the next step is to get a stress distribution, and I get the following error.. which seems to be due to fe_base->reinit(el

Hi, Here is the stack trace for the error that I got. The error happens when build is called to return the pointer to the finite element stuff. This is a simple linear elasticity solver. ERROR: Bad FEType.family= 41 Stack frames: 7 0: 0 libmesh_dbg.0.dylib 0x00010a07591d li

Hi, I get the following error when I try to run my code with FEVector and lagrange_vec elements ERROR: Bad FEType.family= 41 but that is the fetype for the lagrangian vector elements. Is there anywhere that the error could be? Regards, Subramanya G Sadasiva, Graduate Research Assistant, Hierarc

Hi, I have two simple systems. System #1 has two variables (u,v) and the other has one variable (w). All of them are the same order and in the same sub-domain etc. I would like to know a simple method to set the values for w as: w = sin(v) Thank you very much, / Ming Q.
