Error using Real element

[Shubham_Saurabh]

Hi all,
I am unable to parallelize a code with a Real element. The code is running well for n=20. But with increasing n value, I am getting an error of Segmentation fault.

The MWE is-

from fenics import *

n=50
mesh = UnitCubeMesh(n, n, n)
R = FunctionSpace(mesh, "R", 0)
assemble(TestFunction(R)*dx)
print("done")

This query has reference to my two posts-

Consideration of point mass in modal analysis code

Hi @Shubham_Saurabh, You should look at the Ansys manual to see how point masses are implemented and how the equations are modified. I’m not familiar with modal analysis in Ansys so I don’t know how the frequencies are obtained. With that being said, in the results you present from Ansys, it looks like the addition of a point mass has a much stronger effect on the frequency of the lowest-frequency mode than any of the other modes. To me, this suggests that the point mass is implemented via an …

Error while doing modal analysis through parallelization

Hi all, I am performing modal analysis of a 3D box with a distributed mass on its interior faces of cylindrical holes. The geometry and mesh files are here- geometry and mesh . It has DoF of 1.1 million. When I am running it through parallelization , it is giving an error- =================================================================================== = BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES = PID 456 RUNNING AT ec89dea7792c = EXIT CODE: 11 = CLEANING UP REMAINING PR…
