Invalid model

Hi,

Thank you for your help and I really appreciate it. If you don’t mind can you explain what is the issues with the CAD model. Moreover I have encounter new problem.

Using run on - Copy | Other | SimScale model I tried to set internal flow volume but It came up like this.

The problem is that your duct is not hollow - the model fills the flow conduct.

Instead, your model for the solids should only contain the duct walls, leaving an empty space in the inside. Such space will be filled with the flow region operation.

According to this post the the model needs to be hollow for flow region and my CAD has fulfilled that. So, what I should do
