I found this video while doing research for my studies. Great choice of music ;-)
awesome video
Thanks!

Hello thank you for this awesome video, i need a little help in meshing like this pipe integrated in the floor used to heat the air within a small room. and thank you
Hola,
¿me podrías decir por favor la calidad de malla mediante ortogonalidad? Te pregunto esto porque a pesar de la calidad de malla que hayas tenido tu simulación en Fluent convergió!!!, eso es lo que más me sorprendió. EXCELENTE TRABAJO EN GENERAL, AMIGO. (Y)
Gracias de antemano,
Hola Erick;
Si vas a guiarte de la ortogonalidad en tu malla, esta debe ser mayor a 0.15 para considerarse aceptable. Es posible que para valores por debajo aun se consiga la convergencia y eso es posible a que la variacion de los parametros de flujo no sean determinantes en esas zona. Ahora otro punto importante: "El hecho que tu simulacion alcance la convergencia no significa que la simulacion represente los posibles resultados reales". Por ello es siempre necesario tener un experimento o un calculo analítico para contrastar resultados.
Saludos
Buenas tardes. Por lo que estoy viendo los ductos interno y externo, tienen espesor de pared 0, no es así?
Hola Sammy;
Correcto cuando creas la geometria no dibujas el espesor, sin embargo cuando configuras en el ANSYS FLUENT, podemos incluir un espesor aparente el cual sera considerado al momento de iterar. Aqui la tercera parte de este tutorial donde podras visualizar la creacion del espesor de la tuberias: ruclips.net/video/u7x-s0Ud7xU/видео.html

Hello,
Can you tell me the advantages and disadvantages of using thick tubes right from the start? I know that in the Fluent setup this comes into consideration, but why not do the analysis with solid parts? Wouldn't you get more realistic results?
Thank you.
It is a great advantage to avoid creating internal pipes because we save mesh elements and therefore computational cost. However, if you wish, you can consider drawing the pipe and comparing precision and time results, you will see that they are similar or the same. In which cases should you consider drawing the pipe? if you want to know the distribution of temperatures in that area or if the pipe is a source of heat. if it is not the case you can follow this example.
Regards
Hello,
It's not letting me use the Multizone mesh option. Do you have any idea why this can be happening? The error is "MultiZone blocking decomposition failed".
Hope you can help and thank you for the video :)
Hi friend;
Are you using the same example of video?

Sir i am trying to mesh cold plate. How to merge nodes in different parts of geometry?
Hi friend;
Maybe this tutorial can be help: ruclips.net/video/fSbon1Mp-W4/видео.html

Where is adjecent in 19.2
hi ..how do i set the element size in ansys 18.1 ...plz help
Hi friend,
Select Mesh > Insert > Sizing
Select a face a change the Element Size.
Also, you can use the sizing options as this video:
