Hello, I’m experiencing a runtime error when export the equation systems if I use more than one EquationSystems with different variables in each system. In particular, I created 2 EquationSystems: systems1 with one P1 variable and systems2 with two P1 variables. After initializing, I write the EquationSystems on two separate exodus files and here it breaks at runtime. If I initialize the systems with the same number of variables , everything works fine. Do you have any suggestions? I attaching the output error and the simple code I used. Thanks, Simone
