ELMER crash
Posted: 02 Apr 2017, 19:51
Hello,
I get a crash of Elmer solver when solving heat diffusion equation in a system made of 6 bodies in contact, with heat generation in one of these bodies.
Crash is generated by ResultOutput which I want to use to generate a vtu output file for further analysis in Paraview.
Error message is:
"SingleSolver: Attempting to call solver
SingleSolver: Solver Equation string is: result output
ResultOutputSolver: -------------------------------------
ResultOutputSolve: Saving with prefix: case130umcu20um
ResultOutputSolver: Dimension of mesh: 3
ResultOutputSolver: Creating list for saving - if not present
CreateListForSaving: Field Variables for Saving
CreateListForSaving: Scalar Field 1: temperature
ResultOutputSolver: Saving in unstructured VTK XML (.vtu) format
VtuOutputSolver: Saving results in VTK XML format with prefix: case130umcu20um
VtuOutputSolver: Saving number of partitions: 1
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 ffffffffffffffff
VtuOutputSolver: Number of geometry nodes to save: 26238
VtuOutputSolver: Number of dof nodes to save: 26238
VtuOutputSolver: Number of elements to save: 143634"
Modifying SIF file so that ResultOutput is never executed result in a succesfull solve by ELMER, but of course without vtu files being generated.
I used ResultOutput successfully on a simpler geometry (5 bodies, same heat diffusion equation).
Any hint? Might this be a problem with my geometry (although prostprocessing by Elmer VTK seems to show expected heat diffusion and temperature distribution in the geometry)?
Mesh was generated by gmsh if this helps.
