Fluka stopped in Lowset error

Hello, after running my file in Flair, I’m getting the following errors in the .out file:

I’m not sure how to fix this.

Thanks in advance,

Dear Emma,

The issue was caused by a typo. A LOW-MAT card was assigned to compound Mcspt, instead of the Mcplt element.

After fixing the issue get the error you reported in Abort called from DPDX reason NONSENSE GAS/PRESSURE Run stopped!

Cheers,
David
