Hi,

Thanks to all of you for your valuable time and efforts putting in helping others.

I have a solid.And i mesh some facets by 2D automesh.Then i suppress some lines in these facets to improve mesh quality.

But i found when i suppress lines,the original 2D mesh will change,the mesh in facet which lines(suppressed) belongs to will disappear.

However,i need original 2D mesh to do some reference.Now i use *feoutputwithdata and *feinputwithdata2 to store original mesh.But the reading and writing file takes a lot of time.

Do you know another method to fix(store) 2D mesh ?I am very grateful for your help!

Thank you very much!!!

    Hi,

    You have to change default meshing behaviour to 'keep mesh'. You can change it in preferences>Meshing options.

    I think by default it keeps Advanced remesh which is causing this problem.

    However,i find a new problem.If i mesh same facets for twice,new mesh will overwrite the old one.But i need old one to do reference.

    Create a new component and move old mesh :)/emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20' />

    I tried it, but the problem is like that:for the  same facet,only one 2D mesh can exist.Any other 2D mesh for this facet will overwrite the old one  no matter which component it is in.

    Please check whether you are using mesh to surface comp/mesh to current comp.

    It's because mesh is associated to the surf. To break association, translate the mesh a bit, then it will not be overwritten

    Thank you very much!I translate 2D mesh a bit and translate it by reverse direction.Then it breaks association!
