 SYMMETRIC RESULTS TRANSFER FOR TIRE ROLLING ON 1.5m DRUM
 3D HALF TIRE MODEL
 STEP 0: TRANSFER TIRE INFLATION RESULTS FROM
         TIRETRANSFER_AXI_HALF AND GENERATE
         MODEL USING *SYMMETRIC MODEL GENERATION
 STEP 1: BRING TRANSFERRED AXISYMMETRIC RESULTS
         TO EQUILIBRIUM
 STEP 2: FOOTPRINT ANALYSIS (DISPLACEMENT CONTROL)
 STEP 3: FOOTPRINT ANALYSIS (LOAD CONTROL)
