Thank you for your video! It is really useful for me. I want to ask you a things. If there are some protrusionses like vortex generator on cylinder, how we can get meshes like you made in this video? If you answer this question, it will really help me.

Hey Ninja, I was trying to do the tutorial for this mesh, everything works out great until I do the inflation; it rotates the elements inside inflation layer by a degrees creating cells with higher skewness. Do you have any idea what might cause that? Regards

Hi Ninja, Thanks a million for the video! Could you please explain why there's an inflation layer inserted towards the end of the video when there's already a radial bias that was given to the mesh @3:15 ? Thanks!

Amazing!

Once in Fluent, do you merged the fluid zones into one? Or you prescribe the boundary conditions for each of them, in which case, do you need to make the interfaces or the Fluent understand it is all one fluid (multibody) zone? Thanks

Thank you! This is amazing. Is there a way to remove the extra bodies and keep the mesh, so we can reduce the number of zones in Fluent? I had trouble selecting the zones and defining boundary conditions due to the partition.

Amazing But i have one question.. what is the importance for alligning the cells together? like how it affects the solution? Thanks

Thanks friend: When you align the mesh elements you create an ordered structure that allows the computational calculation to be faster if we compare it with an unstructured mesh such as tetrahedral mesh. Best regards

Buenas tardes. Muchas gracias por el video, sin duda es un aporte excepcional. Tengo un problema sin embargo con esta malla. A pesar de que las celdas están perfectamente geometricamente alineadas, el acomplamiento que hace fluent entre los cuerpos genera algunos residuos numéricos. Es posible solucionar esto ? Saludos y muchas gracias !!

Estimado, para evitar este problema debes unir los cuerpos seleccionandolos en modulo Geometry y unirlos usando la opción Form New Part. Esto generará una malla conforme real, sin problemas en las interfaces. Saludos!

@@ansys_cfd Estimado, al parecer esto no soluciona el problema. Estoy haciendo un caso en que se impone un campo magnético al flujo y en las interfaces se generan errores importantes incluso habiendo discontinuidades en la velocidad. Tienes alguna idea de como solucionar esto? Saludos!

The mesh is beautiful, would not it be simpler to use shared topology though? :)

Hi friend, Yes, However, this tutorial was an answer to a subscriber that want to generate this structured mesh type. Regards

Hey Ninja Good job. I am trying to do the same mesh that you have on your video but I have a pipe with diffuser and a nozzle and for some reason I cannot get the same mesh. Also the center pipe has two dimeters. The error is "the meshing has completed but some elements are not compliant with the applied shape" I really need to have the same mesh that you created because I am running a compressible subsonic turbulent flow (hydrogen) but I cannot make that mesh. Do you have any suggestion? Thank you

Buenas tardes, excelente video. Una pregunta Ing. Ivan, si yo quiero mallar solo un a superfice en el msh de ansys, o un solido con el espesor de un elemtno que generalmente se utiliza en simulaicones en 2D por el costo computacional, existe un itpo de malla que sea triangular, que los triangulos sean equilateros y casi el 100 % tenga las mismas medidas (lados del triangulo), (practicamente una malla uniforme compuestos por triangulso casi equilateros) gracias por la respuesta. Nota: Hay un software que realiza eso que es el gmsh, pero cuando se exporta, la malla se mueve un poco con respecto a su origen, y da algunos errores en la simulacion.

Hola Samy, que gusto saber de ti, sobre tu consulta, Ansys por defecto genera una malla estructurada (cuadrados o cubos) para geometrías simples, sin embargo se puede crear una malla triangular usando Face Meshing, esta opción nos permite generar elementos triangulares de igual tamaño, pero no son equiláteros sino isósceles. Si con el Gmsh no funciona, intenta con el Salome, o el ICEM CFD. Saludos

Gracias Ing. Ivan, pude realizarlo insertando un metodo tipo Quadrid/Tri, depois en la opcion All Tri, cambiando la opcion malla controlada por malla uniforme, asi me funcionó, lo estuve intentanto. Gracias por su respuesta, ya que ahora tengo mas opciones a la mano. Espero que con lo que consegui realizar, podria ayudar a alguien mas.
