I have a cast iron vessel that is entirely filled with water (no air space), the water is then heated. Water attempts to expand increasing internal pressure, cast iron vessel expands - both due to the increased water pressure and thermally, creating a larger volume to contain the water which results in lower final pressure than if the vessel was infinity stiff.
Is there anyway to solve this in SimMech ?
Think I need an element formulation / material model for the water that doesn't support shear but does support volumetric thermal expansion & bulk modulus, similar to Ansys's HSFLD242 Elements https://www.simutechgroup.com/tips-and-tricks/fea-articles/158-fea-tips-tricks-ansys-hsfld242-elemen...
Looked at Hydrodynamic elements but they don't support thermal expansion
