Is my result correct? My first time doing simulation with multiple layer of soil.

Hi everyone.

This is my first time doing simulation with multiple layer of soil

Previously I did with only one type of soil for 1m x 1m x 0.1m size of model, the result seem ok.

However, when I did with multiple layer of soil with same model size, the result seems confusing.

I change only the block ROCKS, ELEME and CONNE. 

I insert ELEME and CONNE manually without using MESHMaker. 

So, maybe I did wrong at these block but I already try change there and here but still the result seems wrong. 

TCE saturation seems to move towards right. Why?

Can anyone tell me, where I did wrong?

Attach together input file and simulation result graph for TCE saturation for both simulation.

a) rfs1tce, rfs2tce and rfs3tce is input file for one type of soil

b) rfs1tcehet, rfs2tcehet and rfs3tcehet is input file for multiple layer of soil

c) Comparison graph of result for both simulation
