You need to download the script and then run this script from the downloaded location by going to file > run tcl tk from within HyperMesh. see http://www.altairuniversity.com/support-forum/?mingleforumaction=viewtopic&t=87 you will find this and other scripts in the altair script exchange, go to learning > script exchange from the altair university website or here http://www.altairhyperworks.com/Script-Exchange.aspx?%3ftop_nav_str=1 you will need to log in with your university mail id and login credentials you get after registering to the client centre. search for the script by just entering centreline in the keyword section. once you have found the script click on the download button, once you have downloaded the script place it in a convenient location, then you need to do a file > run tcl tk from within HyperMesh. make sure you have a relevant model loaded in HyperMesh when you run the script.

hy, i have a question. I have a sandwich structure( skin 1 - core - skin 2), Skin 1 and Skin 2 are different layups. i wanted to define skin 1 as a sublaminte, which is symmetric. As secound laminate the core and as third laminate skin 2 also symmetric. There are also a few bulheads in the first skin, thus the global laminate is "heavy" unsymmetric. It is possible to define this in an easy way with the ply based variant without define all symmetric plies double? best regards Mark

Hi Mark, Why you want the skin 1 as a sublaminate? if so, in which laminate is this sub-laminate going? can you shows us a picture or an example with stacking?

Dear Admin, In the attached picture I have connected two components (blue and red) manually. It is taking more time to connect is there any script or option in hypermesh to create by selecting two components respectively which will reduce time. Thanks in advance. Sagar

Hi, There are no universal standard guidelines for modeling bolted or welded joints. Different organizations use different methods for the same. Non availability of standards gives CAE engineer freedom to simulate the things as per his perception & engineering skill. In your case you are creating weld by using solid brick elements so definitely it would take more time. In Hypermesh we have number of method available for weld simulation via rigid + solid/shell element approach. Enter 2d/3d page : connector: Seam Panel For more info after entering seam panel click H on keyboard, this will open the help file for that command. Regards Rahul R

Hi, Do you want to run the command.cmf file in batch mode? if this is the case HyperMesh will run in the back ground and what ever the operation can't be seen on HyperMesh. if you want to see on GUI, run the command file in HyperMesh. go to File>Run>command file to the command file in HyperMesh.

Hello, i try to create some Tube Sections with the following script: #tubesection: 12.7 and 11.9888 *beamsectioncreatestandardsolver 7 1 Tube 0 *beamsectionsetdataroot 1 1 1 2 7 1 0 1 1 0 0 0 0 *createdoublearray 6 11.9888 4 4 12.7 5 5 *beamsectionsetdatastandard 1 6 1 7 0 Tube *createmark beamsects 1 "tube_section.1" *updatehmdb beamsects 1 #tubesection: 12.7 and 11.811 *beamsectioncreatestandardsolver 7 1 Tube 0 *beamsectionsetdataroot 1 1 1 2 7 1 0 1 1 0 0 0 0 *createdoublearray 6 11.811 4 4 12.7 5 5 *beamsectionsetdatastandard 1 6 1 7 0 Tube *createmark beamsects 1 "tube_section.2" *updatehmdb beamsects 1 But when i open HyperBeam to control the outer and inner radius of the sections, HyperMesh just created the first section with the radius of the second and the second has got just the standard radius. Result: Section 1: outerRadius: 12.7 innerRadius: 11.811 Section 2: outerRadius: 5 innerRadius: 4 Do you know how i can solve this problem?

HI h.alpmann, You must change the 1 to 2 in two areas as below :| *beamsectionsetdataroot 2 1 1 2 7 1 0 1 1 0 0 0 0 *beamsectionsetdatastandard 1 6 2 7 0 Tube For the second beam section the first entry of *beamsectionsetdataroot - beam_sect_id i.e. The ID of the beam section to update has to be 2 Same goes for the third entry of the *beamsectionsetdatastandard So your script should be as below :) #tubesection: 12.7 and 11.9888 *beamsectioncreatestandardsolver 7 1 Tube 0 *beamsectionsetdataroot 1 1 1 2 7 1 0 1 1 0 0 0 0 *createdoublearray 6 11.9888 4 4 12.7 5 5 *beamsectionsetdatastandard 1 6 1 7 0 Tube *createmark beamsects 1 "tube_section.1" *updatehmdb beamsects 1 #tubesection: 12.7 and 11.811 *beamsectioncreatestandardsolver 7 1 Tube 0 *beamsectionsetdataroot 2 1 1 2 7 1 0 1 1 0 0 0 0 *createdoublearray 6 11.811 4 4 12.7 5 5 *beamsectionsetdatastandard 1 6 2 7 0 Tube *createmark beamsects 1 "tube_section.2" *updatehmdb beamsects 1

i tought i must declare all laminates with the same typ http://www.bilder-upload.eu/show.php?file=9d476d-1386160399.jpg here you can see an easy sketch, red: skin 1 symmetric white: core(as shell mat2) green: Skin2 cyan: core of the bulkhead yellow: skins: bulkhead all skins and cores are shells with an exact free shape on top of skin 1. I tried to define the laminate like in example I_Beam_Composite_PCOMPP (Exercise 2.3)

In the above program, defined force vs. crank angle in curve option. Then in the force definition used curve option selected the defined curve and for the independent variable selected "AZ" of the crank shaft body. Not sure whether this is the right approach! Second thing, how to measure the inclined angle of crank and specify it as the independent variable . Whether cylindrical co-ordinate system to be crated to specify angle or cartesian co-ordinate system is sufficient? Whether AZ is appropriate command for specifying angle in cartesian co-ordinate system? Pl. clarify

Hi Rahul, thank you very much. I got it. I had to use an autoit-script to produce an HW-ASCII file for a transient analysis and now it works :) Regards Emad

hi, is the curve plotted between force and crank angle? what is the component in selected in curve? Assuming it as crank angle, you can write a independent variable function as MOD(AZ) instead of just AZ.

Hi, In the below force statement, attribute fx_curve_id, fx_interpol_type, fx_indep_var are not MotionSolve attributes. Which tool you used to generate this xml file? <Force_Vector_OneBody id = "30101" type = "ForceOnly" marker_id = "30105052" ref_marker_id = "30101010" fx_curve_id = "301001" fx_interpol_type = "LIN" fx_indep_var = "AZ(the_model.b_2.id)" fy_expression = "0" fz_expression = "0" /> Regards Rahul R

Hi, it looks a bit tricky. You can create three sublaminates (Skin1, core, skin2) and create a interface laminate. what is the thickness of the core? have you considered using solids instead of shell for core? Do you have the geometry for the model? if yes, can you share with us? please use the dropbox below: https://ftin.india.altair.com:8443/filedrop/~BDR1DN

Thanks guys.I was using Google chrome and it wasn't showing the examples section for some reason. Now I use a different browser. These examples are really helpful. However I haven't found a tutorial on explicit analysis where they use a force vs time curve loading or acc vs time as loads. Can you please recommend a good tutorial for that...

In examples, example 18 deals with force Vs time please refer to that. Also please refer to examples where you see imposed velocities, imposed displacements, imposed acceleration (time dependent). this gives you good idea on time functions, curves :)
