Dear All,

Iam using Netgen in batchmode and verbose mode and iam able to import a Step geometry and perform geometry healing ,Surface mesh generation as well as volume mesh generation.

Here are some queries i have regarding the same:

Healing:

1. Import Step geometry --> Perform geometry healing. After performing healing Save geometry as a Step File. Changes in geometry after healing are not stored in the newly saved step file (For Example Change in the length of short edges)

2. Import Step geometry --> Perform geometry healing. After performing healing Save geometry as a IGES File. Netgen is CRASHING.

Mesh:

Batchmode :

1. When using Netgen in batchmode , there are options to provide local mesh sizes and refinements using two different files i.e, meshsizefile and refinemetinfofile. But there is no sample file or syntax given to write these files.

2. While using netgen in batchmode, As in Verbose mode there is no option provided to generate only surface mesh. By default , netgen batchmode generates volume mesh.

General:

1. I wanted to load a stl surface mesh file and then generate a volume mesh for the same file.
steps:
After generating surface mesh for a geometry , save the mesh in STL mesh format. Now to import this stl mesh file, there is no option provided. Then i tried to use Load geomety option to import this stl file, but the mesh points and surfaces are not loaded.



Thanks in advance.
