How to configure the memory In Flux?

This document gives some explanations about how configure the memory in Flux.

How to drive Flux with compose?

Altair Compose software is a numeric computing environement which allows to: plot datas, implement algorithms for scientific computation.

How to experiment with NumPy in Flux?

NumPy is a Python module widely used in scientific computing area and could improve the capacity of what Flux users could achieve when they write PyFlux scripts.

How to get the steps of a scenario?

Some API have been implemented to allow the user to select steps to quickly postprocess. All methods have been added on the structure SCENARIO.

How to import a HyperMesh mesh?

HyperMesh is a software from Altair which is dedicated to the pre-processing. You can find all the tools to achieve your geometry and mesh it.

This document describe the steps and advices to export the mesh from HyperMesh and then to import it in Flux.

How to import a SimLab mesh?

SimLab is a software from Altair which is dedicated to the pre-processing. You can find all the tools to achieve your geometry and mesh it.

This document describe the steps and advices to export the mesh from SimLab and then to import it in Flux.

How to launch Flux via command line?

This document gives some command lines available to launch Flux.

How to set Flux for batch schedulers?

This document will provide the necessary knowledge to be able to set Altair Flux up for a canonical use, i.e.: solve one large-scale project using distribution with allocated resources.

How to use external Jython classes in Flux?

Sometimes a user would like to extend the capabilities of the python scripts run by Flux for example to access a database.

This often requires to add third party jars to the classpath of Flux so that those third party classes become available in the Flux Jython session.

How to use Flux with PBS?

How to use Flux with PBS via Display Manager?

Flux offers the possibility to use PBS Professional Compute Manager to compute distributed jobs. The possibility to post-process the solved projects located on your cluster is now available through Display Manager.

How to use the coupling Flux-AcuSolve with the Import/Export Context?

Flux-AcuSolve coupling allows to make thermal analysis in AcuSolve by taking the losses computed in Flux (Joule losses or Iron losses) as heat sources.

This specific document gives the optimal workflow to follow in Flux and AcuSolve to make the thermal analysis of a cable

How to use the coupling Flux-OptiStruct with the Import/Export context?

Flux-OptiStruct coupling allows making NVH analysis or static analysis in OptiStruct using the magnetic forces exported from Flux.

The various concerned applications according to the coupling are: Motor, actuator, busbar ...

This specific document gives the optimal workflow to follow in HyperMesh, Flux and OptiStruct to make the NVH analysis on a motor.

How to mesh skin effect?

Best practices: The modeling of magnetic core made of laminations

This document describes different calculation modes that take into account the magnetic cores made of laminations in the 2D and 3D Flux models.

Best practices: How to adjust Mesh locally?

Aided mesh permits the rapid execution of a good quality mesh.

When the « aided mesh » does not permit the user to obtain the desired mesh quality (physical not taken into consideration, too dense mesh etc.), the user should alter the mesh information locally.

This document gives some strategies of local adjustment of the mesh as a local adjustment strategy is not always apparent.

Best practices: Thermal analysis of electrical machines

This document gives help to use the modelling of Electrical machines.
