ANSYS Meshing & ICEM/CFD
Meshing Overview
The ANSYS software suite is providing a large variety of different meshing applications, methods and approaches. The following table is an attempt to provide to LRZ users a short outline of the available meshing capabilities:
ANSYS Application | Meshing Methods | Suitable for... | Recommended Computer System for Meshing |
---|---|---|---|
ANSYS ICEM/CFD | ICEM/CFD Hexa - structured hexahedral meshes ICEM/CFD Tetra - unstructured tet/prism meshes |
| |
ANSYS Workbench | ANSYS Meshing (incomplete list):

ANSYS CFX |

ANSYS ICEM/CFD Meshing on RVS
Since meshing of a geometry is a memory intensive application, it is highly recommended to use the LRZ Remote Visualization Systems for running ANSYS ICEM/CFD. Furthermore, most meshing applications require hardware (OpenGL) graphics support for a reasonable user experience with the software.
Once you are logged into one of these LRZ Remote Visualization Systems, you can check the availability (i.e. installation) of ANSYS ICEM/CFD software by:
> module avail icem
Load the prefered ANSYS version environment module, e.g.:
> load module icem/2023.R1
Run ANSYS ICEM/CFD on the LRZ Remote Visualization System with OpenGL support:
> vglrun icemcfd
ANSYS Workbench Meshing on RVS
ANSYS Workbench and many contained ANSYS software components had been developed exclusively for Windows OS and only afterwards ANSYS made the attempt to provide ANSYS WB on Linux systems using Mono. Consequently ANSYS WB itself and some of the contained software components behave rather unstable on Linux OS, also the LRZ RVS is currently operated under an officially supported Linux OS (SLES 12). With the anticipated change of the LRZ RVS operating system to Ubuntu LTS in the near future, we expect that ANSYS WB and all software components which are provided in ANSYS WB exclusively can no longer be provided on a future LRZ RVS. Already today ANSYS Spaceclaim is not contained in ANSYS WB on LRZ RVS, since ANSYS Inc. is not providing a Linux version of Spaceclaim. Standalone software components like ICEM/CFD, ANSYS CFX, ANSYS Fluent and Ensight are not affected, since they are provided with GUI's natively running on Linux OS (not Mono based).
So therefore ANSYS Geometry Modeling (ANSYS DesignModeler) as well as ANSYS Meshing methods are available only through the platform of ANSYS Workbench. They cannot be run as standalone applications. ANSYS SpaceClaim is not available on Linux OS. ANSYS SpaceClaim is an application which is available on Windows OS systems only.
So, once you are logged into one of these LRZ Remote Visualization Systems, you can check the availability (i.e. installation) of ANSYS Workbench software by:
> module avail wb
Load the prefered ANSYS Workbench version environment module, e.g.:
module load wb/2023.R1
Run ANSYS Workbench on the LRZ Remote Visualization System with OpenGL support:
> vglrun runwb2
From within the ANSYS Workbench schematic launch the ANSYS Meshing application with appropriate geometry import (CAD file, ANSYS DesignModeler geometry modeler). ANSYS Spaceclaim is not available on Linux OS.
