Re: fem analisys on carbon tube frame gmesh warnings...

So if I want to do a fem analysis on a carbon fiber tube system from dragon plate. I would get the tube properties and assume the aluminum connectors are similar in strength. Then I should boolian join them by making the parts that connect make one side larger. ? The overlap could even represent the...

Re: fem analisys on carbon tube frame gmesh warnings...

I will soon thanks it's great to know those are working. And thanks for showing how it was fixed in git I like how it version controls. Can things be assembled and fem Ed?
