I thought I read somewhere (I can't find it anymore) that flow sim has a Mach 3 limit? Is that correct?
There is a high mach number solver option for numbers above 3. Check out S-043191 in the knowledge base.
How do I find the knowledge base? This:DS Support Knowledge Base is the only "Knowledge Base" I can find and searching the provided document number does not provide any results.
Does the high mach number option work with mixed high/low mach number systems? I am simulating a converging/diverging nozzle. The high mach number option appears to make it harder to converge on the low mach/converging section of the nozzle. Any advice is appreciated, thank you
No, is is SOLIDWORKS Knowledge Base. https://customerportal.solidworks.com/ It will require you to add product using your serial number to be able to access the KB.
There is some info in the Flow Simulation help file about it.
High Mach number flow
Select this check box if you want to analyze high-velocity gas flows (flow Mach number is greater than about 3 for steady-state and 1 for transient analyses). The High Mach number option is applied for the entire computational domain and cannot be changed for an individual fluid region. You cannot select the High Mach number flow option if some Real Gas is selected as one of the Project fluids or the calculation of relative Humidity is enabled (see below).
See also High Mach Number Flows.
It should work with domain with both high and low numbers, but if you are having issues with it, suggest that you contact your VAR.
