Different Vmodeled of SSA and HO

tyl

Dear all,

I successfully processed SSA model and it showed Vmodeled similar to Vinput, however when I extrude mesh and reprocess with HO flowequation the Vmodeled is much bigger (40 times) than Vinput and the pattern is totally different. I also tried modify number of layers but seems not helping.

Any suggestion?

Hi Allen,

it is very hard to tell without looking at the model. Most likely, your Vz is too large. Can you do

plotmodel(md,'data',sqrt(md.results.StressbalanceSolution.Vx.^2 + md.results.StressbalanceSolution.Vy.^2))

and compare that to the obs? If it looks good, it is definitely Vz.

Best

I follow PIG tutorial so initial.vz is 0. Is it a problem?

I just check initial Vx and it is much smaller than modeled Vx.

The initial vz does not matter here. What do you mean by Vinput, is it vx_obs and vy_obs?
