Wave model cannot be initialized, error code -1 - Forum - Delft3D Flexible Mesh

Hi,

I am running an given example wave model with Delft3D FM (2021.03). The model can be validated but after running the model, the initialization of waves fails because of Error code -1 and it did no generate a diagnostic file. The run report does not give much information too.

I am sure the model is set properly since it is a example wave model, and my colleague was able to run the same model just fine.
Does anyone know what this error code means? Is there a way to diagnose and fix the problem?

Thank you in advance.
