Hi everyone.

I´m doing a simulation of a scheffler type solar colector and I want to export the optical simulation results into mechanical to be able to do a thermal simulation using the irradiance capted in the sensor but I can't find a way to achieve this.

The optical simulation


Workbench view


The results I want to export


Reference geometry on which I would like to measure the heat distribution, maximum temperature, convection losses, etc.

Thnaks.

Hi, 

I would recommend using a 3D irradiance sensor instead of a 2D irradiance sensor, for the following reasons:  

 

1. 2D irradiance is only placed on a virtual plane, there is no mesh on this plane. 

 

2. On your solar collector, you probably need absorption on it but a 2D irradiance sensor has no optical property to get this information. 

Here’s a suggested workflow to perform a SPEOS – Mechanical connection:  

In speos: 

 

1. Named Selection group is the key element to correctly perform a Multiphysics simulation between Speos and Mechanical.  

• Make sure you have created an NS for each component you want to analyze. 

 

• Make also sure these groups are applied to each geometry (assign your material with Groups, not bodies) 

 

 

 

 

2. XM3 data export: 

 

In Workbench: 

• Geometry imports from Speos to Mechanical -> Use External Data block to import data exported from XM3 -> Thermal block allows to manage thermal simulation in Mechanical

 

 

Then you can perform a thermal simulation (in this example is a steady-state thermal simulation but it depends on your project)

Hi, Thomas, thanks for your answer and sorry for the delay.
I have been trying your recommendations but after I export the XM3 file to mechanical using the external data block I get error in the weighting’s box:

After I got this error in the mechanical interface when I run the simulation: Current Weighting option is not supported by all the input meshes.

Here is the workbench workflow:

The external data block:

And here is the SPEOS interface:

Which could be the mistake in my simulation? The purpose of the simulation is for recolect heat, and temperature information in the focus.

Thanks for your attetion.

Hi,

The described workflow was actually for SPEOS / Workbench from the 2022R1 version. Your setup seems to be correct but it won't work with your 2021R2 version.

Could you please try again with 2022R1/2022R2?

Note: here i'll try again to send you the description with images

In speos:

1. Named Selection group is the key element to correctly perform a Multiphysics simulation between Speos and Mechanical.

• Make sure you have created an NS for each component you want to analyze.
• Make sure also these groups are applied to each geometry (assign your material with Groups, not bodies, i didn't see the details in your screenshots by the way)

2. XM3 data export:

In Workbench:
- Geometry imports from Speos to Mechanical -> Use External Data block to import data exported from XM3 -> Thermal block allows managing thermal simulation in Mechanical

Thanks, Sen!
