Hello, I'm a new PetraSim user with relatively no experiance with this type of program but I've been attempting to learn it for the past 5 months. I've gone through the ThunderHead tutorials without too much trouble but recently when I try to run almost any kind of simulation I run into some problems. These problems consist of random system crashes before running the simulation, no production of output files, and inconsistancy with running previously functional simulations. I was wondering if there were any updates coming out soon to fix these kinds of problems or if there was anything I could do myself to mitigate them.
To add on to this topic, I've discovered what actions bring out these errors: Editing material data after a simulation run, editing materials of grid layers, and rerunning a simulation after editing in Solution Controls.
Solution Found: Going through a reinstallation fixed most of the problems, I assume there was an error in the initial download of the program. Still occasionally throws out a "Fatal Error" but way better now.
