Valves & flow control
Valve, manifold and flow-control simulation
Pressure drop and flow coefficient through valves, manifolds and internal passages, the cavitation and choking that show up at real operating conditions, and the stress in the body that contains them. Compressible and incompressible cases sit in the same tree, so a choked condition is a change of case type rather than a change of tool.
Questions this answers
- What is the pressure drop, and the flow coefficient, across this valve?
- Does this cavitate at duty, and where?
- Is the flow choked at this pressure ratio?
- Is this manifold distributing evenly across its branches?
- Does the body hold at pressure and at temperature?
The analysis types that do it
Each of these is a case type in the application, not a configuration you assemble. Every one runs in the free build — the free tier limits mesh size and cores, never which physics you may use.
And in the other modules
Structural, thermal and electromagnetics ship alongside fluids. Only the types that run today are listed.

Open-source solvers, selected and configured from the case type. You can still read every dictionary the application writes.
When it will not fit on your machine
Paid accounts can send meshing and solving to SHD Cloud and keep working locally. The estimate is shown before the run starts.
What this does not do
- No moving valve members. A travel sweep is several cases at fixed positions, not one case with a moving plug.
- Fluid–structure interaction is not coupled; pressure loads are transferred by hand.
- No standards-based Kv or Cv reporting — the pressure drop is computed, the certificate is not.
Naming a sector here says the physics suits the work. It is not a claim that anyone in it is a customer.
