 || Nested simulation - numerical issues || 27/12/2019 ||  || Nested simulation ran for 1 minute. However, large oscillation in the u- and v-component could be observed within the child. I hypothesize that this is due to the 3D-initialization of the child from the parent. Due to mismatches in the building configuration (due to the large grid aspect ratio), many grid points in the child remain zero after initialization, even though these grid points belong to the atmosphere. Since the mass-flux is largely affected by this, strong oscillations arise within the child, finally lead to a crash. ||
