Title: Pleated filter element with pleat deformation
Post by: Mark on September 18, 2025, 02:11:43 PM

Dear GeoDict-Team,
I would like to calculate the flow through a deformed fold. Can FlowDict and ElastoDict be coupled for this purpose? Or is there another option?

Dear Mark,
at the moment, a direct coupling between ElastoDict and FlowDict is not possible.
A possible workaround is to simulate the pressure drop in FlowDict and use the resulting pressure as the load input for an ElastoDict compression simulation.
Please let me know if you need any further information.
Best regards,
Lilli

Hello Lilli,
I assume that the pressure I can define on individual steps in ElastoDict is a static pressure that is effective throughout the entire calculation area. How can I define a pressure drop across a pleat that I have created with PleatGeo?

Best regards
Mark

Hello Mark,
yes, your understanding is correct. The pressure is applied throughout the complete structure. But for some applications you can approximate the pressure drop by applying pore pressure to the material on one side of the filter (e.g. inner side of the pleated filter). You can apply pore pressure in ElastoDict under Deformations – Macroscopic Load Case – Fluid Pressure.
In this workaround, it is important that the material on the other side of the filter is not defined as pore anymore, but e.g. as a very soft solid. Otherwise, the pore pressure would work here, too.

Best regards,
Lilli
