Hello guys,

I am trying to perform a simulation on ANSYS FORTE of a 2 stroke engine. I followed their tutorial, but in the tutorial the geometry was already ready, so I just needed to import it to FORTE as STL file. The problem is: now I tried to do my own geometry on Design Modeler, but I can't export this geometry in any type of file that FORTE can import. I opened the geometry on ANSYS Mesh and create the named selections and then tried to export it as STL File, but it is possible just if I gerenate the mesh.. and FORTE generates it automalically. I generated the mesh there and exported, then I imported the STL file in FORTE and it didn't work. Do you guys know how to create a geometry to use in ANSYS FORTE?

Yes, I did. But then I faced other problems later. I gave up using ANSYS FORTE. It is good and everything but very hard to use. You need to go through many specific steps to make it work. You have to look for these steps in separate places (ANSYS Tutorials). When you have ANSYS FORTE opened, there's a button there that you can have access to these tutorials. Good luck!

Thanks for the fast response! I followed some of the tutorials and also read the theory manual from ansys but at the tutorials the geometry its pretty simple or its provided in .stl, do you still remember how u managed to import from spaceclaim or other cad?

Thanks in advance!

Btw im brazilian and it seems you are too so if u really are and wish to speak in portuguese no problems haha

Opa, beleza.

Então cara, eu não tenho certeza. Tenho duas memórias sobre isso e não lembro qual tinha dado certo.

Lembro que uma coisa que fiz foi criar a geometria no DesignModeler. Essa geometria tem que ser só de faces se você for usar o recurso de meshing automática do ANSYS FORTE. A orientação das faces tem que ser no sentido que não tem domínio de fluído. Lmebro que tinha que nomear as faces (create named selection) para já ficar certinho no ANSYS FORTE. Depois de criar esta geometria, eu abri a mesma no Spaceclaim. No Spaceclaim, na aba Facets, é possível transformar as faces em facets. As faces vão ficar iguais a de um CAD STL. Depois, é só fechar o Spaceclaim e conectar esta geometria como input no setup do FORTE. Eu não lembro se isso tinha dado certo e nem se foi exatamente isso que fiz. Eu teria que gastar um tempo tentando fazer isso de novo. No fds eu tento.

Outro coisa que tentei e não lembro se deu certo foi criar a geometria no DesignModeler do jeito descrito anteriormente. Depois abrir esta geometria no Meshing e criar uma meshing nas faces. Não pode esquecer de criar as "named selections". Daí, não lembro se extrai do meshing em algum formato (STL, por exemplo), ou se conectei a saída de meshing no setup do FORTE.

Enfim, dependendo do que você estiver modelando, existem varias regras Best Practices que vc vai ter que seguir. É bem complicado.

Porra trabalhoso deixar certinho a geometria pra ele, queria importar pelo menos o cabeçote do motor que ja tinha desenhado no spaceclaim, vc por acaso foi do baja?(pretendo simular o motor serie 19 caso tenha sido)

Agradeço demais ai pela ajuda cara, dificil achar coisa do Forte na internet e parece ser bem fresco ele, vou dar uma olhada no best practices tbm.
Eu to abrindo o motor aqui pra desenhar as coisas que faltam e no fds devo tentar deixar isso certinho, vlw demais por se dispor até a tentar fazer dnvo pra ver oq da certo mas sei que consome um tempao essas coisas, se n for de boas precisa nem esquentar que eu tento e te falo oq deu certo aqui.

Eu fui do baja, porém não trabalhei com motor.

Cara, eu gosto muito de simulação, então não me importo de ajudar. Qualquer coisa ajudo no fds. Só mandar msg no linkedin. Se quiser dps detalhar melhor o projeto, tento ajudar com mais esforço.
