Hello,

I posted earlier the following problem: /forum/forums/topic/preconditioned-conjugate-gradient-solver-error-level-1/

And used all the suggestions I received from peter.

However, I got a different error this time.

An error has occurred in the Distributed Sparse Matrix Solver while factoring the matrix.  Error code = 17

Attached the log information

 The solution stopped during the 3rd step which at this step I was receiving this warning:

THERE IS TOO MUCH PENETRATION AT   42  CONTACT POINTS OF THE 3D CONTACT ELEMENTS

Hi bolbol,

In the majority of cases, this error occurs due to disk space being full - either the total drive space or the allocated space within the user account folder (Scratch directory). Please make sure that you have adequate hard disk space available for the run.

If you can confirm that there is enough disk space, first determine if the analysis will solve w/o error in Shared Memory Processing (SMP) mode (i.e., Uncheck Distributed Solution in Home tab->Solve). If this solves, then you can also try Distributed Memory Processing (DMP) mode as well.

Moreover, I have some suggestions for reducing the problem size. You can try adding some biased mesh sizing to only refine the mesh close to the contact region, as shown below

Plus, it is always a good idea to run a coarse mesh model first, and after you rule out all the convergence issue, you can refine the mesh. 

Regards,

Wenlong

Hello Wenlong,

- For the disk space, I've checked it. there are still 300 GB free.

- The distributed solution option was activated, I shall try again while disabled, correct?

- The solution works fine with coarse mesh, I increased the number of elements to 1 million in order to get more accurate results.
