Cite 5 … Web6 Apr 2024 · The diffusion coefficient was 9.46 × 10 −11, where the diffusion effect was sufficiently small. The initial condition was C = 1 for the entire LV at the beginning of diastole in the fourth cycle ( t = 0.3 s) and C = 0 for the mitral valve, where the blood flowed in, and the zero-flux condition on the wall was given on the LV wall. geelong flyer transport shepparton

Get Your Scalar UDFs to Run Faster Without Code Changes

WebIf your simulation was done in Ansys Fluent, you can do it in Fluent as a post process calculation with user defined scalar. Define a mass uds, add cell zone uds source as the fluid density, set inlet diffusion for uds as 0 and then solve the uds. No need to solve other equations as it does interfere with them. Web6 Mar 2024 · More often than not, a Compute Scalar simply defines an expression; the actual computation is deferred until something later in the execution plan needs the result.
