 June 20, 2014, 07:08 About cylindrical mesh and the credibility of result #1 New Member   Join Date: Feb 2014 Posts: 8 Rep Power: 5 Recently,i have been trying to work out a complicated problem with one couple moving object driven by one compression spring.As can be seen from the picture,the most part of the computational domain is axisymmetric,except for the inlet section.So,i intend to use cylindrical mesh.If necessary,i will tinker with the non-axisymmetric component. Here is my questions. What parameters should we modify if we change the Cartesian mesh to the Cylindrical one? How about the coordinates of sampling volume and two end pionts of spring? How about the moment of inertia tensor about mass center in body system? If we don't extend the cylindrical mesh to 360 degrees,should we cut the value of spring coefficient by the corresponding proportion? The second problem is how to measure the credibility of result. Select the Analyze > Probe tab, and under Data source select General history.Among the variable names,there are three variables named component * GMO z-pressure force in space system,component * GMO z-shear force in space system and component * GMO fluid z-force (pressure+shear) in space system,respectively. Should the sum of the first two variables equal the third one? Can anyone please help me? Thanks!
