HPC Model Review: Difference between revisions

The first step of reviewing a HPC model is no different to reviewing a TUFLOW Classic model. Start by opening the TUFLOW log file (*.tlf) and confirm at the bottom of the file, that the model run finished successfully by observing "Simulation FINISHED" and that the final mass error reported is acceptable as shown below:<br>

 

Though HPC is volume conservative and shouldn't produce any mass error it is still important to review the Mass Error, as it can still occur when coupling HPC with 1D elements in either the 1D/2D linking, or in the 1D itself.<br>

A 'healthy' model will usually report up to 1% mass error. Higher mass error is an indication the solution is not converging, usually in isolated locations. In nearly all cases it is because of poor data (e.g. cliff edge between data sets) or model schematisation (e.g. large pit connected to one tiny 2D cell or boundary poorly digitised so it is not roughly perpendicular to the flow). The total model mass error can also be observed in the TUFLOW Summary File (*.tsf) output as oppose to the tlf file. <br>
