Peregrine unable to solve for surface load on irregular shapes

Hi, I am new to peregrine and been testing it on my projects. For whatever reason, when I try to solve for a surface load solution with an irregular shape, it results in crashing the program. The alternative method of dividing many points to apply many point loads yields a solution but it looked completely messed up.

The file is attached here and hopefully there is a fix for this. (21.8 KB)
