I am a newbe to Comsol. In order to master the Comsol, I am trying to slove one of the available one's in Comsol library. In the "Optimization of a Tesla Microvalve" I am trying to define all things by myself through the function library. I downloaded following file: https://www.comsol.com/model/optimization-of-a-tesla-microvalve-14513 tesla_microvalve_optimization.mph - 1.58MB
Until "material" everything goes well. In page 9, in Laminar flow (spf) on item 3 it says: In the settings window for Inlet, locate the Boundary Conditions section. In item 4 it says: "From the list, choose Laminar inflow" However "Laminar inflow" doesn't show up in the drop down list. Is it because I haven't done somthing in the past steps? How can I solve this issue? TIA
