In WF4 Mechanica, I keep getting a fatal error after the analysis has begun with the alert: "Highlighted solid element has singular mapping".
When I validate the mesh beforehand, it doesn't give me an error then. And the highlighted element never looks unusual.
What the heck is singular...
I've recently noticed that Mechanica will mesh using any datum points in the model. As I am analyzing a fan blade with 4500 datum points (for profile curves) and I really don't want the mesh to be that fine, how do I tell Mechanica to not mesh using datum points?
The work-around I currently...
I am wondering if drag coefficients apply only to moving fluids (dynamic pressure) or if they can also be used for calculating force on an object due to static pressure. The static pressure in this case is due to static pressure rise across a normal shock in a supersonic wind tunnel.
The...
Is the specific heat ratio (isentropic expansion factor) of a gas mixture simply a molar weighted average of the individual heat ratios? If not, how is it calculated?
I apologize if this is not the correct forum for this question. The other forums that might be more appropriate seem to be...
I am trying to find a machining process for making 63,000 very small (.020” dia) holes through .200” thick 6061 aluminum with .050” layer of epoxy (Scotch-Weld, Shore D hardness = 55) bonded to it. Hole spacing is .056” resulting in 318 holes per square inch. The holes do not have to be...
In my system, which is supplied by a 2200 psig, 50 Liter Nitrogen bottle, I am required by NASA safety requirements to use two pressure regulators in series in case one fails.
I need to size a relief valve which will be able to handle the flow at the downstream pressure (55 psia). Although I...
