In a 2D Mesh I assigned an aquifer thickness of 10m. For choosing the right Influx... Do I have to  calculate my flux by J/m/d that means do I calculate W/m²*10m*86400s/d or is it enough to just calculate W/m²*86400s/d always in mind I set 10m aquifer thickness in the Heat material Menu..

Thank s alot

The first setting would be the correct one. The value has to be multiplied with 10 m as FEFLOW uses depth-integrated values in case of a confined 2-D model - therefore the unit J/m/d. Be careful with such a boundary: If you also have fluid inflow at this boundary, you'd have to use the divergence form of the transport equation.
