Meshing Pressure Vessel - Tips Needed

Meshing Pressure Vessel - Tips Needed

Meshing Pressure Vessel - Tips Needed


I`m trying to mesh a simple pressure vessel as shown in the attached picture.

Ideally I`m looking for quad meshing and to control the number of elements through thickness. I`m not very familiar with the advanced functions yet and the ones I tried resulted on errors.

Could anyone with expertise on this matter point me the right path?

PS: I know I could do a 2d axisymmetric analysis for this, but I plan on increasing the geometry complexity, so I`d need a 3D analysis.

RE: Meshing Pressure Vessel - Tips Needed

First you need to slice your model in quarter or half segments to have through thickness element control. You have to force method probably Multizone on the bodies with all quad option.

For info on meshing check this Link and this Link.

Thank you NRP99. I sliced my body on quarter segments and was able to mesh the cylindrical part the way I wanted.

Having some trouble on meshing the hemispherical part though. I`ve seen images where people are able to mesh it hex dominant, but I getting errors when trying to do it.

RE: Meshing Pressure Vessel - Tips Needed


With multi zone meshing (method) and by using a proximity mesh for the global size function (instead of adaptive), a HEX dominant mesh (with possible control on the number of elements you want to have through the thickness - defaults to 3) can be generated.
For more information on this see: https://studentcommunity.ansys.com/thread/how-to-g...

Another way to control the elements through the thickness, is by defining Mesh sizing option specifying the number of divisions say along the four through thickness edges of the two cylinders.
Then no need to set the global size function to proximity, just use adaptive. So in this case one needs both a multi zone mesh for all bodies and mesh sizing on the 4 edges.

These two methods will work if you have a multi body part, consisting of e.g., two end caps, and two cylinder parts.

Hope this helps - Erik

RE: Meshing Pressure Vessel - Tips Needed


I managed to get my mesh done using your tips. However, when I imprinted some faces on my cylindrical body the multizone started to give me errors, but I managed to overcome it by doing nothing (i.e. deleting the multizone) and a structured mesh was created.

White Paper – Choosing the Right Spring Loaded Connector
In today’s cost-sensitive world, designers are often driven to specify the lowest cost solution for every aspect of their designs to ensure that their solution is competitively priced and their company remains profitable. However, specifying a low-cost, low-quality connector solution can result in premature failure, considerable re-work costs and damage to reputations. Download Now
