RepeatCurrentTimeStep_AdditionalComputationsAfterDataTransfer

additional computations on original pointcloud after data transfer is finished

As the repeating of the current time step happens after the original time step is already finished, we need a means of computing additional values on the original pointcloud. WE MUST NOT use CODI_eq (see CODI), as this function is processed DURING the executions of the original time step.

RepeatCurrentTimeStep(n) = ( %RepeatCurrentTimeStep_BasedOnSamePointCloud% ) # repeatine based on the same pointcloud RepeatCurrentTimeStep_ChangeCVconfiguration(n) = ( "ord_laplace=2" ,0, "ord_gradient=2" ) # set the approximation order (temporarily to 2 for the repeated time step) RepeatCurrentTimeStep_SaveVariables(n) = ( %indU_v(1)%, %ind_v(1)%, # define data trensfer from temporary to original point cloud %indU_v(2)%, %ind_v(2)%, %indU_v(3)%, %ind_v(3)%, %indU_p_corr%, %ind_p_dyn%, %indU_c%, %ind_c% ) # perform additional computations on original pointcloud, based on the data transferred RepeatCurrentTimeStep_AdditionalComputationsAfterDataTransfer(n) = ( %indU_Dv%, [ sqrt( (Y%indU_v(1)%-Y%ind_v(1)%)^2 + (Y%indU_v(2)%-Y%ind_v(2)%)^2 + (Y%indU_v(3)%-Y%ind_v(3)%)^2 )] , %indU_DpCorr%, [ abs(Y%indU_p_corr%-Y%ind_p_dyn%) ] , %indU_Dc%, [ abs(Y%indU_c%-Y%ind_c%) ] )

In the example above,we compute the difference between the velocity, dynamic pressure, and correction pressure solutions between the original time step and the additionally performed time step. The results of the computations are written to the index variables %indU_Dv%, %indU_DpCorr%, and %indU_Dc%, respectively. ATTENTION!!!!!!! The additional computations are executed regardless of the order as they appear in the brackets, i.e. dependent solution cannot be produced. The following example

RepeatCurrentTimeStep_AdditionalComputationsAfterDataTransfer(n) = ( %indU_A%, [ ... ] , %indU_B%, [ ... ] , %indU_C%, [ Y%indU_A% + Y%indU_B% ] )

is constructed wrongly, as we presume a dependence of %indU_C% on %indU_A% and %indU_B% which cannot be provided by RepeatCurrentTimeStep_AdditionalComputationsAfterDataTransfer .
