'Mumps' - Increasing ICNTL14 - Openseespy

[jrbnewcastle]

Hi All,
I am receiving the following error:

WARNING MumpsParallelSolver::solve(void)- Error -9 returned in substitution dmumps()
Work array too small; use -ICNTL14 option, the default is -ICNTL 20 make 20 larger

However if I try to increase the ICNTL14 in openseepy by using e.g.:
ops.system('Mumps','-ICNTL14', 80)

But still get the same error message, unless I reduce the number of processors.

Does anyone have an example of calling this in OpenseePy?

Many thanks in advance.
Kind regards
