The OPAL Discussion Forum

Dear Sir/Madam,

I am currently working on simulating the spiral inflector and central region of a cyclotron accelerator using the OPAL. To calculate the beam loss, I need to import the geometry of the spiral inflector electrode and central region into my simulation.

In OPAL, I understand that the GEOMETRY command  can be used to import geometry file information in H5hut file (e.g., Geometry, FILE="input.h5"). In the paper "Realistic Simulation of Cyclotron Spiral Inflector within a Particle-in-Cell Framework", it is mentioned that the geometry can be meshed using GMSH software. However, I could not find any detailed explanation on how to convert the GMSH-generated mesh into an H5hut file for use in OPAL simulations. 

Additionally, I was unable to find relevant information in the OPAL manual (Chapter 20 Geometry)  regarding this conversion.

Could anybody kindly share any methods or tools that convert a GMSH mesh into an H5hut file? Any insights or advice would be greatly appreciated.

Thank you very much for your time and consideration. I look forward to your response.

Best regards,

Xi Chen
