OK, i got it.
If one does not state explicitely that the Domain-Decomposition-Solver should be used, the direct solver is invoked, leading to the behaviour described above.
The problems i had stem from using input files from an older ABQ-version + Umat. With input-files generated with the...
Hi,
i already thought about this, and tried to write an iges-file by hand. The syntax/scheme is somewhat difficult. i think i have to get a CAD-Program.
bye,
sorry, i forgot to mention that the only difference between the nicely running job and the neg. eigenvalue party is that i (un)comment the mpi_host_list in the abaqus_v6.env file. so a compiler and abaqus-version conflict can be discarded.
Hello!
I have the following problem: Jobs that run nicely on a single machine produce massive negative eigenvalues and fail when submitted to a parallel environment involving multiple machines.
I am using a user material subroutine, that does not contain any MPI-related functions. I thought...
Hello!
I would like to construct a 3D-Cell-structure in ABQ. I have the gemetric data onhand, like
V1: 0 , 0, 3
V2: 8.4 , 0 , 6
.
.
.
v10: 0.4 , 0.2, 0.4
Cell 1: convex hull of V1,V2,V5,V6,V9
Is there a ABQ function or script command that allows to create in a simple manner parts...
