I am calculating Talor Green vortex. I find the initial kinetic dissipation rate experience an increase. Anyone meets the same question?

12 December 2015 0 9K Report

The kinetic dissipation rate should start from a small value, but my results start by a relatively large value, decrease some time steps, then increase as the correct way.

I check the code, but don't find any problem. Anyone has an idea?
