Hellow everyone,

I'm now working on the vortex induced vibration of submarine pipelines.
I want to study the VIV characteristics of the pipeline, but when I set the gravity of the pipeline to be equal to the gravity of water, the pipeline will sink, and this will make subsequent analysis inaccurate.

I can't find a value that will make the pipeline still in water.
I wish anyone could help me.

What do you mean by set the gravity of the pipeline equal to the water. There is only one place you can set the gravity that is at Physic > gravity. I believe u try to say here is density. Am I right?

If by geometry > density, u need to use the formula, density = mass of the pipe (kg) / volume of the pipe (m3).
