I'm trying to program a mohr-coulomb cycle calculation for silo flow analysis, but I'm having a hard time with some functions. They can help.File not found.File not found.

If you click on the region that has the element highlighted you see an hint about the isse (xyz not defined).

In detail, this is triggered because in those regions you have requested an inline result with numerical output, and this can't be done if there are variables not defined or symbolical.

You can still show a result if you set the regions optimization to none or symbolical, or in new regions you use CTRL+. insted of = to get a symbolical result.

Your document does not open.
Failure to open has been reported, but never clarified.
Maybe something in there from unrecorded Originator.

Your document is fine.
File is last saved with SMath v0.99.7822.147, it opens perfectly on SMath v0.99.7921.69.
If SMath config directory is cleared, can be opened even with SMath v0.98.6179.21440.
There will be a lot of problems but who cares, v0.98.6179 is a 5 years old SMath build.
Nobody should be using it still and nobody should complain about it can't open newer files.
