Mriganabh,

 

I doubt contact models were created for HEX20 elements. This is a good question to ask for the MOOSE group.

Subject: [EXTERNAL] [mastodon-users] HEX20 elements with Contact Block

 

Hi all,

 

I am trying to run the example 6a on the MASTODON website with HEX20 instead of HEX8. I encountered a Segmentation Fault while using the "opt" version of MASTODON. Upon running the same input using "dbg" version, the following error was shown - 

--------

/home/borumrig/projects/mastodon_lemhi1/moose/scripts/../libmesh/installed/include/libmesh/dof_object.h, line 978, compiled Jul  7 2020 at 11:51:56

[cli_32]: aborting job:

application called MPI_Abort(MPI_COMM_WORLD, 1) - process 32

Assertion `comp < this->n_comp(s,var)' failed.

comp = 0

this->n_comp(s,var) = 0

--------------------------

This makes me wonder if it is even possible to run simulations with HEX20 elements & Contact block?

 

Thanks,

Mriganabh

Hi Chandu,

Adding the following lines to the contact block seems to fix the issue -
