    Hi Vipin You can use "by block" option in *createmark. Here is sample code. set blockname [::hwat::utils::GetUniqueName block "Dummy"]; *createsimpleblock $blockname 11 -100000 -100000 0.5 100000 100000 100000; *createmark surfs 1 "by block name" $blockname; *numbersmark surfaces 1 1; *createmark blocks 1 "by name only" $blockname; *deletemark blocks 1; Thanks, Imoto

    Yes surface is not a named hypermesh entity. If you tagged the surf in catia. Maybe the tag will be imported into hm as metadata. Try searching it by: set md [hm_metadata findall] puts [join [lsearch -all -inline -glob $md "surfs $surfID *"] \n]

    The virtual wind tunnel you show in your screenshot if very small for any reasonable aerodynamics results. You might get colorful picture, but probably no useful interpretation. Wind tunnel dimensions: o 5 car lengths ahead of the car o 10 car lengths behind the car o 5 car widths on each side of the car o 10 car heights above the car o i.e., wind tunnel dimensions LWT x WWT x HWT = 16Lc x 11Wc x 11Hc. o The mesh farther away from the car will be coarse and increasing the wind tunnel domain would not affect the element count too much but it would still affect the B.Cs if they are too close to the car.  Boundary Layer details o First layer height will depend on the freestream velocity to obtain a maximum y+<100. A first guess would be 0.2mm<y<0.5mm. Ideally y+max<30. o For some applications y+max<100 should still give good results o growth rate of 1.3 o number of layers 5 o all tets in boundary layers

    I'd like to share the seamless integration that Compose with other HyperWorks applications, such as HyperMesh and OptiStruct. In order to expose the Compose function to other HyperWorks applications, we need to register the function. This is done clicking on the right mouse button on Register Function in Compose: After this step, we may now see that the function has been registered under the same mouse click shown above under Show Registered Functions button. Once it is registered, we may now use it inside other HyperWorks softwares, and the function will be available without the need for closing and reopening the application of interest. Example in HyperMesh: Why Compose and HyperMesh? Matrix Browser queries and modifies HyperMesh and HyperView data entities without writing cumbersome TCL coding, along with a Math method developed in Compose. Example in HyperGraph: Why Compose and HyperGraph? Plotting capabilities of HyperGraph are expanded with Compose’s advanced functions and custom procedures developed by the user. Example in HyperView: Why Compose and HyperView? Advanced post-processing or special mathematical approaches may be applied directly on the model. Example in HyperStudy: Add a new output response Define a new expression Use your custom Compose function Why Compose and HyperStudy? User-defined functions to perform design exploration and optimization. Example in OptiStruct: Why Compose and OptiStruct? User-defined functions to perform optimization with DRESP3 card (desired response based on external files). Regards, Roberta

    Hi, We can use tool edges to create feature elements all along the free edges of your model, these can later be used to create shell cross sections and change the configuration of these feature elements to create 1D feature models of the original solid or shell models. https://altairuniversity.com/wp-content/uploads/2013/09/Tool_Edges_TTF.pdf Plotel elements can also be converted into CBAR and CBEAM elements. https://altairuniversity.com/wp-content/uploads/2017/03/1D_Elements_Extract.pdf

    Okay, it kind of got solved. For everyone who has thr same issue. The System or the Mateial orientation dialog does NOT work for this. (2017.2) However you can create a coordinate system und put it into the property as CORDM. Select "USER" and choose the coordinate system. The materila will orient itself around the X-axis.

    1. The idea is to use the 2D mesh to impose a mesh pattern on hexa mesh. If you want a specific mesh pattern in the through-thickness direction you can also 2D mesh the sides and use nodes or elements as guides (elems to drag/match, along geom). Note that imposing mesh patterns in 2 directions requires well thought out meshing plan as it needs to be 2 directionally mappable. Maybe you will find videos on solid map helpful . 2. surf geom in the case of provided screenshot can be set to none, because it is already defined by elems to drag. Select the surface opposite to the 2D mesh as dest geom. Please hit the like button on useful tips

    When you use hm_pushpanel to invoke panel "automesh" to help user to adjust mesh, hm_pushpanel will return soon and not wait for user finish his work. => do not use hm_pushpanel, you need to pack all remained script into hm_setpanelproc example: eval *createmark surfs 1 $::FlangeSurfs set Holes [p_GetHoles surfs 1] hm_entityrecorder surfs on p_SplitHoles $Holes hm_entityrecorder surfs off eval lappend ::FlangeSurfs [hm_entityrecorder surfs ids] hm_setpanelproc { hm_setcollector automesh [hm_getcolnumber automesh 1] surfs hm_initpanel { eval *createmark surfs 1 $::FlangeSurfs hm_activateitem [hm_getitemnumber automesh mesh] } hm_callpanel automesh eval *createmark elems 1 {"by surface"} $::FlangeSurfs p_SolidMap elems 1 }

    Hi, For a fixture design, it depends on the operating frequency range on which the system is tested. You can for keeping the natural frequency around 1.5- 2 times of the operating frequency. If you are going for a component or system level design, understand the range of frequencies to which it is subjected to. For understanding local frequency effect, try running the frequency response analysis.

    CBUSH is a generalized spring-damper structural element with can take up to 6 stiffness values.If there are more than one stiffness we need to assign a local coordinate system id. What exactly you want to capture with zero length Bush element?I have attached some documents from user guide for your reference. CBUSH.pdf PBUSH.pdf

    Hi Michel, Sliding contact might not work using linear static analysis. In linear static analysis, the contact status does not change, does not slide and the contact stiffness is constant throughout. It is advisable to equivalence the sheet panels to the core instead of using the freeze contact. The load and consequently displacements are so high it can be solved more efficiently in Radioss. Given the loads and BCs are symmetric you could reduce the model to a quarter for computational efficiency. I have set up your model with imposed displacement of 10mm using NLSTAT analysis. 3PB_edit.hm

    Hi, I definitely agree with qchen regarding the doc :-) I have a similar question: I'm trying to import one of my scripts (imprtScrpt.py) in another script (mainScrpt.py). The imported script only contains functions. The only solution that I've found until now is to call "executeBatchSpy('imprtScrpt.py')" in mainScrpt. When I simply try "import imprtScrpt", mainScrpt exits without any message. Am I doing something wrong? Thank you very much in advance for your help! PS: until now, I've been ok with importing by using executeBatchSpy, but my script is starting to get quite big and I'd like to use imports to use profiling tools (such as doxy).

    Hi again @Premanand Suryavanshi I tried to resolve the issue with simple model and I meshed the inner surface as well. in following I adopted linear solid mapping as shown in figure 1 and found it useful with settling issue (figure 2). Many thanks for your considered time and your extreme guidance. Sincere thanks again Good luck and blessed

    Hi Pablo I I hope you have done 2D tria mesh using Automesh. For doing an volume tetra mesh, the mesh should be an enclosed volume ie; No free edges. Try fixing the free edges and check for equivalence. Go to Tools > edges and check for free edges and equivalence nodes if any If that doesn't work, share your model please

    Hi, For a bus roof structure which generally has thickness in the range of 2-2.6 mm and if we go for tet mesh for it, the lower element size will also cause reduced element time step but when you model it with shell elements, the minimum element size can be taken as 4 to 5 mm. This gives more time step when compared to the tet mesh. This being one of the reasons, shell mesh is used for complete bus structure.

    As mentioned above its a CFD mesh.(Octree hex mesh) Octree approach is useful when you have a very poor cad and tricky surfaces. Use this approach when you do not want to spend more time cleaning cad model. On the other hand, advancing front requires less user input to generate a good mesh, but it does require good quality CAD surfaces and tricky surfaces sometimes don't mesh. You can refer wiki on how the Octree algorithm works. http://en.wikipedia.org/wiki/Octree The Octree based tet meshing introduced in version 13.0 is a faster and high quality alternative to the proven advancing front meshing algorithm, and can be used with more than just CFD applications. And due to the logic behind this scheme it provides a very nice BL transition. It can be accessed through the 3D page  tetramesh or CFD tetramesh panel  Tetramesh parameters option.
