Hello . I realize a 1D / 2D model I have difficulties with the stability of the model. After a simulation here are the errors that appear. thank you to answer me.
Plan: ‘Simulation1’ (MODELE_1D_2D.p01)
Simulation started at: 16Feb2017 04:41:50 PM
Using 64 Bit Computation Engines
Writing Geometry
Surface: Mesh property tables are current.
Completed Writing Geometry
