  Does this run locally on your pc or does it run in their servers? What are the specs of your pc?

  This runs locally on my pc. I have an AMD Ryzen CPU and decent amount of RAM (which is rather important for topology optimization): 128 GB But I see it run successfully on old laptops too. Speed is obviously different then.

  Hey, there is also a way to visualize the reaction forces in the GUI of Inspire for the optistruct solver. You just need need to move the reaction slightly, like a remote load, you can do this in Inspire where after you have defined the support it gives a triad. After doing this you can click on the reaction force call out like you would for bolts or fasteners. If you are curious about this let me know, I can shoot you an image. I have gotten this question on support tickets a good bit. Thanks!

  Would you explain what is different between Altair hyperworks and Altair inspire..

• 
  @ManuelRamsaierАй бұрын

  Sure thing. In short, Inspire is targeted at the CAD engineer with stress calculation afinity. Its easier, well automated but limited in scope. Hyperworks has been renamed to Hypermesh and this is the full feature Preprocessor for the stress calc guy. Much more detailled, more functions etc. So, for a quick look at things, quick optimization: Inspire is a great tool. If you want to have detailled control and / or a more diffficult setup, then use Hypermesh.

  Thank you very much for this channel, by training I am a mechanical engineer working in the mining and mineral processing industry in South Africa. I have developed a great love for programming as well as thermodynamics and fluids after I worked on a project where the bearings on a ball mill were running hot and leading to failure. Having checked numerous drawings and machining tolerances we could not resolve the issue until the bearings were changed. No fault was detected in the manufacturing of those bearings though. I have thus decided to study in greater detail these two disciplines of fluids and heat transfer.

  @@AbuIshaq1441 In meiner Erfahrung ist es so, dass du dir deine Zeit bei der Promotion frei einteilen kannst. Das Problem hier ist eher, dass die Promotion und das Projekt (von welchem du bezahlt wirst) nicht immer den gleichen Inhalt hat und du dann die Promotionsthemen quasi in deiner Freizeit machst, nachdem das Projekt bereits bedient wurde. Du kannst bei der Promotion dich so viel einarbeiten, wie du möchtest. Da gibt es in meiner Erfahrung keiner, der das dir verweigert. Wichtig ist eher: Es gibt nicht immer jemanden, der dich anspornt, das fertig zu machen. Die Promotion ist deine Sache und du musst das so vorantreiben, dass am Ende eine fertige Arbeit entsteht. Es ist ein Reifungsprozess auch gegenüber deinen Betreuern, der in der Abnabelung endet. Wenn du eine fixe Deadline für die Promotion hast (bspw. Industriepromotion) ist es nicht selten der Fall, dass man das nach der Zeit noch fertig macht (neben dem Beruf) und erst später abgibt. Zeit ist hier nicht das Problem.

  Hi I am sorry for out of topic Did you know why the Hypermesh is so heavy application I have Hypermesh 2023 suite in my PC (Ryzen 5600X, 16Gb RAM, RTX 3060 12Gb). My computer lagging so much even if only I import geometry The geometry is a simple small 1Part (motorcycle shock absorber head) Actually there is nothing suspicious in the Windows Task manager (CPU 10~20%, RAM 50%) I don't know why this can possibly happen Is there anything that I can do to make the application lighter?

• 
  @ManuelRamsaier2 ай бұрын

  Hey :) Can you describe a bit better what you mean with lagging? A delay when importing the geometry is completely normal. Even small geometric parts can be heavy to import as for example the number of faces which Hyperworks has to facet can be large even in small parts. If you want I can test it on my machine if you send me the geometry file to [email protected] If the lagging is related to turning of the model, make sure you have the latest gpu drivers installed. Your machine is suited well for the job. I have a similar one as you do.

  Hallo Manuel, I have been wanting to add curves in hypermesh using tcl script and I did not find any syntax for importing the values through csv. Would be great if you could help.

• 
  @ManuelRamsaier4 ай бұрын

  You have to look it up in the command.tcl file when you are doing it in hyperworks. For a simple curve TableD1 its like this: *createentity curves name="curve1" *setvalue curves id=1 STATUS=2 12300=1 *setvalue curves id=1 STATUS=2 12301=2 *curveaddpoint 1 $counter $x $y where $counter, $x and $y are what they say: so for example: *curveaddpoint 1 0 1 0 this adds the first (index/counter 0) point at x=1,y=0 and so on. if you have a csv file you have to go through there line by line and add the points with tcl. You can also write a python converter which reads the csv and puts out the tcl for you.

  Hi, I hope to don't bother you with a question not related with this topic. I am simulating a bolted connection between two components in an assembly with rbe2. Do you know how it is possible to extract the force reaction that the rbe are subjected to? I tried different output card, like SPCFORCE, but since these connection are not SPC they are not visible. I tried GPFORCE but without a free-body diagram it shows no values. I am now trying with MPCFORCE but still struggling. I work also with Ansys and there it is very easy: once you set the connection (in first approximation I assume that the faces in contact are bonded) you can easily request as output the reaction forces and moments that the two faces of the connection exchange. Thank you very much, i really appreciate your tutorial, learning Hyperworks alone is very challenging.

• 
  @ManuelRamsaier5 ай бұрын

  My best bet would also be with the mpcforce. Its not a reaction force as you dont have a boundary condition there. It depends how you model your bolt. Is it just a rbe2 connection for the entire bolt or do you create rbe2 in the lugs and connecting them with a cbeam (for example)... you can send me the model to [email protected] and I will have a look at it.

  Hey, das ist in der Tat eines der Schwierigkeiten. Jedoch wird die Topologieoptimierung auch gerade in Serienteilen richtig mächtig, da die Gewichtseinsparung ja dann auch die ganze Serie betrifft (Automobil und Luftfahrt sind da die dominanten Felder). Topologieoptimierungen werden schon stark verwendet, das Ergebnis dessen jedoch meist nicht 1:1 umgesetzt. Einfaches Beispiel: Stell dir irgendeine Art Hebel vor, welcher leichter gemacht werden soll. Anstatt stumpf Löcher reinzusetzen, kann dir die Topologieoptimierung (in dem Fall 2D) sagen, wo und wie viele und wie groß die Löcher aussehen sollen. Die kannst du dann aber auch einfach Fräsen. Die bionisch anmutenden Strukturen sind zwar dann nochmal ne Liga drüber von der performance aber man macht oft Abstriche der performance um Herstellbarkeit zu gewinnen.
