[FAQ]

The information described here are convenient if you want to specify cells with a particular cell skewness in Tgrid. You can automatically split cell zones above a certain skewness by entering the following text command.
/mesh/modify/separate-cell-by-skew
If any cell zones are above the specified skewness threshold, they will automatically split. It should be noted that Fluent has an equivalent function. With Adapt/Iso-value, you can enter a threshold value with Grid > “cell equivolume skew”, and then divide the zone with the skewness that was specified. This process will work effectively for initialization. This function cannot be used as it cannot be initialized if the skewness of the mesh to be read in Fluent is equal to 1.
