Line 10: =Is recalibration necessary if I switch from TUFLOW Classic to TUFLOW HPC?= Yes, if transitioning from Classic to HPC (or any other solver), it is best practice to compare the results, and if there are unacceptable differences, or the model calibration has deteriorated, to fine-tune the model performance through adjustment of key parameters. <br> <br> Typically, between TUFLOW Classic and HPC 2nd order this would only require a slight adjustment to Manning’s n values, any additional form losses at bends/obstructions or eddy viscosity values. Regardless, industry standard Manning’s n and other key parameters should only be used/needed. Use of non-standard values is a strong indicator there are other issues such as inflows, poor boundary representation or missing/erroneous topography. <br> <br> A greater adjustment of parameters would be expected if transitioning between HPC 1st order (or the original TUFLOW GPU) and Classic or HPC 2nd order.
