Unknown error feflow version 8.002 by generate mesh whether 2D or 3D

Dear all, when I want to generate a mesh whether in 2D or in 3D (TetGen) Feflow says "unkown error" when I push the "generate mesh" button. I follow the online tutorials "Getting started with groundwater modelling" and "Advanced modelling of complex geologies" of Feflow step by step and don't know maybe in this version I have to check any other option or something. I don't think that the input data is problematic. Input Data in 2D: I generate a Supermesh with the polygon tool. 3D: There was already a .smesh-fiile i downloaded of the training portal. Can anyone help me? Best Anne

Hi Anne, I think you have a license problem. Can you please check under Tools - License and verify whether there is an available FEFLOW license? In the case, you would like to use Geode-FEFLOW Tools, you would also need a FEFLOW Advanced license? Best regards Carlos Rivera

Thank you! I activated my license in this version again and it is working!
