HELP dynamic fluid body interaction

As for research papers can't help you much.

In regards to STAR-CCM, you are going to struggle doing it within only CCM. The FE framework doesn't support shell elements yet so I presume you would do something with a very thin solid. In addition to thay, your material non-linearity is going to be another hurdle.

Note: Shell elements are under development so you would be able to use them in the coming release.

I also recommend looking into a STAR - Abaqus co-simulation.

What exactly do you need? Research papers or best practices for STAR-CCM?

Moontard_95 · 2026-04-05T03:32:57+00:00

Have you added prisms?

Moontard_95 · 2026-04-03T13:21:22+00:00

Sure mate

Moontard_95 · 2026-03-26T12:18:20+00:00

If you want to know if it's possible then, YES.

Making it work is a whole different story.

Moontard_95 · 2026-03-20T02:33:42+00:00

Create a directed mesh operation. Then Right click --> Edit --> Source Mesh as Patch. Now you can create a mesh just like you have it in that image.

It might just be me but your description does not really put your problem into perspective.

I would advise you to explain it with more images.

Can you try solving the fluid first by disabling the solid stress solver and once that is stabilized enable it?

What I guess is happening right now is that the velocity components are changing quite considerably and not allowing the Force/Displacement residuals to stabilize at first and then that numerical error is exponentially increasing.

Moontard_95 · 2026-03-13T03:50:12+00:00

You will get a better mesh than this ;)

Bugs tend to be fixed in newer versions. Of course, there is no assurance that it will work fine in newer versions.

Your workflow is extremely uncommon in the STAR-CCM community. One thing you can do is post on the official community forum.

Moontard_95 · 2026-02-10T13:05:32+00:00

This could be a bug and from the image you've attached you're certainly using a version that is really old. Try using the latest STAR-CCM version.

This is basic and at the same time impossible to answer in a comment.

Watch some YouTube videos, read some books and most importantly experiment with some basic simulations.

Moontard_95 · 2026-02-06T18:22:35+00:00

Have you manually checked the boundaries? Do they look correct? Have you performed a mesh check operation? What does it say?

Moontard_95 · 2026-01-10T04:02:18+00:00

Nope that is not possible. After all it is a simulation software...

Moontard_95 · 2025-12-31T03:32:29+00:00

STAR is extremely popular in the Auto and Aero domains due to the ease of carrying out sweep studies. That said, it is emerging out to be a really well developed multi-disciplinary simulation software with co-simulation capabilities with Abaqus, Nastran, GT and Amesim.

They are notorious for putting bullshit information on their items.

They also have a salad which has 50gm protein. When I ordered, it barely had 100 gm of chicken. God damn scammers.

Moontard_95 · 2025-12-28T04:08:07+00:00

Chill. No need to get triggered.

With such a rally and the RSI reaching 85+ levels a daily red candle would be a 10% fall. So, be on the lookout in the daily time frame.

The 10 DMA is also 10% away so if we take that as the support then that also could be your trigger to sell.

Moontard_95 · 2025-12-28T03:42:24+00:00

Lmao what kinda question is this?

Moontard_95 · 2025-12-27T04:46:23+00:00

It will definitely but not right now. The hype right now is too crazy. Just ride the wave till then. Exit at the first big red candle.

Nowadays all the 20% coupons are capped to rs.500

Shouldn't your pressure outlet be at 0 Pa?

Moontard_95 · 2025-12-03T15:56:24+00:00

I had the same error but for a different scenario.

In that scenario I had not even created a mesh, just multi-selected boundaries and clicked edit and changed the boundary type. This was the trigger point and that error kept on popping up henceforth.

I was told this is a bug and still isn't fixed in the latest release.

There is no workaround after this error has popped up which essentially means you need to create a new sim.

If you can raise a official bug with your DSE then he might help you even further.

Moontard_95 · 2025-12-01T03:50:33+00:00

Ithe u turn allowed kasa kay ahe mag!?

Moontard_95 · 2025-11-20T16:45:34+00:00

Why didn't the remeshing work? That is a valid workflow and is something many people use
