Week 2 Challenge : Surface meshing on a Pressure valve
In this pressure valve model first we started with topology cleanup and geometrical errors. after that we started with checks in check option we started with geometry check, after geometry checks we go with there is one option called visible, in that visible option selected after selection we excute different different check over there, After that all check did on after that we excute that, then its showing some errors. that errors like single cons and cracks. Then we started with single cones to fill the volume one by one. after that we checked where single cons is there , then we started to fill that one . for filling we are using option that one new, in new there are four surfaces is there. then we started to filled one by one surface used.After filling the all surface again we did checked geometry check then all the errors is clear.
After topo cleanup, we checked some visibilty like single cones, double cones and triple cones.In model before meshing we seen the model small small surfaces is there,whose created by design engineer to maintain the shape in that surface.when we do meshing that small surfaces will be interfere. after that we checked distance between two surfaces. it's very less distance came. when we do mesh the larger element will not match properly because of less length. so we did small surface remove by cut option to get proper element.after that we removed all small surfaces.
After we started with pid manager, when we seeing the model it will be pid mode.after that there is a option called pid manager in the top.after we opened the pid manger, we seen one pid assigned that is called shell property and that pid thickness is 1mm and then material id is 2. in order to create a pid we have to do right click after that new then pshell after one popup box will be come after we create name outlet.same way we created one by one pid nad we changed the pid colour also.after that we need to assigned the pid. we have to right click over the outlet after that we have option called apply then we have to select over the cross-section of the suface after i will do middle click.after that same way one by one pid assigned.after we assigned all pid we delete shell property.
After we started with mesh, before meshing we have to give mesh length then we have to click length ,in that one we have to give first perimeter length then marcos length after we have to give mesh parameters, in mesh parameters we have to give target length after that we have to give minimun length and maximum length and also element type tria .after that we have to go quality criteria, in quality criteria we have to give minimum length and maximum length after that we did meshing one by one.
In challenges they given target length 1mm, 3mm and 5mm and element type tria after that we given one by one target length and we got output.
