Error writing transient results in FSI
Hello,
i am trying to run a transient Fluid Structure Interaction on a rocket nosecone geometry consisting of 2 bonded solid bodies of different materials submerged in one fluid domain. My predecessor got it to run in ANSYS 11 (at least his report says so), but i have to use 12.1 since there are supposed to be several improvements in the multiphysics field. However, i get an error whenever the solver tries to write its first set of transient results: +--------------------------------------------------------------------+ | Writing transient file 1_CS_full.trn | | Name : Transient Results 1 | | Type : Standard | | Option : Every Coupling Step | +--------------------------------------------------------------------+ +--------------------------------------------------------------------+ | ERROR #001100279 has occurred in subroutine ErrAction. | | Message: | | Length of variables list is not consistant in parallel. Routine G- | | ET_VARLST called from routine Write_Soln_Fcs. | Google doesn't even know this error, and i myself have never encountered it before in any of my other FSI-Simulations (which only use one solid body). I defined both exposed faces of the nosecone+can as one FSIN and coupled it to the fluid domain. The Solver is running on a 4-Core XEON machine with 16GB Ram in local MPI. Does anybody have a clue what this error message tries to tell me? Is it a setup error or a mpi error? If you need more info, i am happy to provide. Thanks for your help, Daniel |
Ok, it seems to be a MPI error. When i run the Simulation on 1 core, it works perfectly fine.
