Contour Visualization of MIKE 21 FM results

Hello,

I have a question about visualizing the results of flood simulations with MIKE 21 FM.
Looking at the maximum water depth in Mike Zero the mesh elements are often not completely wetted with water due to the elevation of the mesh, especially at the edges of the flooding area. The results in Mike Zero show the contours.
For the processing of the results the results usually have to be available in a GIS. Using Mike2Shp leads to results where each element gets only one height, which is an erroneous and unsightly presentation of the results.
How can one achieve a comparable representation in Arc(GIS) similar to the contour visualization as in Mike Zero based on the MIKE 21 FM results?

Many thanks and greetings
Sebastian
