I am using SVFlux together with FlexPDE 5.0.23. I am working on a 3d model of a railway levee, which is irrigated on top with a zflux boundary condition for 15 minutes. The banksides of the levee are set to Review Boundary Conditions. When looking at the zflow plot across the top surface, the amount of flow is too high (-4.1 m3/h). The zflow is set to 0.00005 m3/m2/h, which should yield to 0.0081 m3/h for the area given. What would you suggest to change in the code? I have set all FEM option parameters to the default values.

My concern is that the boundary condition shouldn't be switched on at once. I have read a posting where you suggested using a RAMP boundary condition. How would the code have to look like? With the code below, there is a wrong number of arguments. Surface 5 natural(uw)= RAMP(t,(uww*(0))*Normal(0,0,1)*sign(Normal(0,0,1),(uww*(0.18))*Normal(0,0,1)*sig n(Normal(0,0,1),0.0167). | |||

We need to see the FlexPDE script. You can post it here, or email to support@pdesolutions.com |
