 Hey, 

This is my first time using Ansys to run a simulation. For my project I'm just trying to run a simple simulation on an assembly with a large number of parts. I'm trying to run a simulation on a heat exchanger, but I can't get it to mesh correctly. I have tried preparing the object in spaceclaim but it doesn't seem to be enough. Does anyone have advice on how I can prepare this assembly further to make the mesh generate properly. For instance I don't know how to just remove or substitute problematic parts. I'm already using a mesh size of .01m. Any advice would be helpful. Here is the error list

It would help if you inserted some images of the geometry and show some images of the mesh.

Here is the mesh pic, I believe inside the heat exchanger there are small tubes that are causing the main meshing issues. That and possibly the screws due to their threads. This is a mesh larger mesh size that I used just to send a picture.

Hello mspinazz,

Thanks for the image attachment. In the picture you can see two parts shown with yellow colour (there could be other parts also hidden inside but from image two are visible). These are the one which are causing problem. Change mesh settings for these parts to see if it works: May add body sizing with appropriate mesh size based on features on these parts, may try making off adaptive sizing and adjusting growth rate, defeaturing propeties. I am just citing few sample tries to check.

Thanks
