Hi every body, 

For lighting luminaire simulation, I want to test the effect of color of the body of the luminaire on the results. I want to try several colors. My first idea was to prepare as much simulation as colors I want to test, and launch all the simulation at the same time, but it appeats it's not possible. 

 

Somebody has a good trick for this? 

Thank you.

Hello,

There are several solutions, the most efficient depends on the number of materials to test. You can either export a simulation for each material and run these from Speos Core. Or you can record a script that automates the material change and run the simulation for each.

Cheers.

Thanks Mathieu for your answer, 

For now, scripting is a little bit too complicate for me, and I'm not very used with the "SPEOS Core" tool, I discover it with your answer. Is it possible to put several speos file in it, in order to chain the calculations?

Thank you!

Hello,

There is also a possibility using Workbench.

First in Speos, go in Workbench tab and click Publish Parameters. Then select the material and tick in the row Publish corresponding to the material file (the value is a path to the file)

Then launch Workbench. Darg and drop a Speos toolbox in the project schematic like this 

Right click on Geomety then Import Geometry and select your Speos project.

Right Click on Simulation Task and click Generate Parameters.

The project is automatically open and Workbench retrieve the parameters. A link parameter set is added under the Speos node

Double click on parameter set

On the right part, there is the ‘Table of Design points’. Here you can  right click on DP 0 and duplicate it as many time as you need (number of configutations) and on each new design point (DP) you can change the file name

Save the project. 

Back to the project tab, you can Update all design points (will work only if you have an output paramete) or  when parameter set is selected, chande in the propertie Retaiend Design point to Update full project like this :

Then you can update all design points.

Workbench will create one folder for each confuguration with the project corresponding to this configuration and launch the simulation. 

In each subfolder you can find the result for each configuration. 

 

When selecting simulation task, in the propertie you can also choose the GPU solver

 

Best regards

Thomas

Thank you Thomas for this very complete and detail answer, I will try it as soon as possible, like the scripting method. 

I found an alternative before the weekend (a good time to launch several calculations): I create as many copies of mechanical parts as necessary, and I apply to each one a material to test; ditto for the sources if I want to calculate with several sources. 
"I only have" (the most difficult and long part) to create as many simulations as necessary, selecting the right geometries and the right sources. 

Effectively, the best would be that I master the scripts.

 

Regards, 

Maxime

You can start scripting with something simple like this:

And then elaboorate with an Excel File:

Speos API: ANSYS SPEOS Automation 2023 R1
