Error message when reading inp mesh file generated from Ansys

Versions

Below is my FLUKA and Flair versions.

FLUKA: 4-5.1
Flair: 3.4-3

Description

Dear FLUKA experts,

I am attempting to follow the instructions for the new FLUKA capability of unstructured meshes using Ansys ( 3. Generation — FLUKA unstructured meshes mini guide ), but am encountering an error message, which I am unable to decipher.

Here is my attempt with the snowman example, which was provided in the geom_mesh_utils package. I have first generated a mesh of the CAD file in Ansys and then wrote the “Solution” to an input file (see below). Then I attempted to bring the Ansys-generated input file into FLUKA via the UMESH card but encountered error messages, which I am unable to make much sense out of. Any assistance or advice would be greatly appreciated - thank you!

Input files

Attached are my FLUKA input file and the Anysys-generated input file.

Hi @ted.liang,

Good news, there is no issue with your mesh.

The problem is that Flair treats this file as an Abaqus mesh due to the extension:


Simply change the extension of your mesh to .cdb

Best regards,
