Dear all,

I was able to solve successfully some problems in elasticity in 3D.  
Mesh is extremely simple (a revolved square, so forming a ring).  
However, as soon as I increase the number of nodes and elements, I get the error :

“Error umfpack\_di\_solve status -3”

I noticed that other users experienced the same issue but I was able to find no answers.  
It cannot be a memory problem since I have RAM 32 Gb and Windows 10 64bit and the memory occupied by the solver is just a tiny fraction before it gives the error.

To understand the problem, I tried to repeat the Example “beam-3d.edp” that I find in the examples/3d subdirectory.  
I replaced line 4 :

int[int] Nxyz=[20,5,5];

with the following:

int factor=4;  
int[int] Nxyz=[20 \* factor, 5 \* factor, 5 \* factor];

with factor up to 3.5 there is no crash, and very little memory occupation. However, it crashes with factor from 4 upwards, even if the number of elements and nodes is still very low.

Do you have any solution?  
Many thanks in advance
