    Ok, so basically you want an user input to decide which type of selection must be used. This can be done in a variety of ways, using simpler forms or the more elegant ones with graphic interface. Using a simple yes or no question, this would be like so: set answer [tk_messageBox -message "What type of load would you like to input? \n Yes: Force \n No: Pressure" -type yesno -icon question] switch -- $answer { yes { "Code for Force load" } no { "Code for Pressure load" } } If you want to have something nicer (which requires more work), you can use for example a radiobutton. But in this case you need to build the hole interface for the user navigation like confirmation and return buttons and maybe even other options. A code snippet to use a radiobutton would be like so: #Get preview frame set w [hwtk::demo::getpreviewframe] set w [hwtk::frame $w.frame] pack $w -anchor nw -padx 4 set ::feedback "" set ::currentLoad "Force" pack [hwtk::labelframe $w.lf -text "Select the type of Loading" -padding 2] -anchor nw foreach load {Force Pressure} { pack [hwtk::radiobutton $w.lf.b$load -text $load -variable ::currentLoad \ -value $load \ -command "set ::feedback $load" \ -help "$load"] -side top -pady 2 -fill x } pack [hwtk::label $w.label -text "Active Load:"] \ [hwtk::label $w.label1 -textvariable ::feedback] -side left -pady 4 Hopefully this is helpful.

    There is a variety of functions you can use to achieve this: *elementtestaspect Help hm_createmark elems 1 "greater than value" "aspect 3" Help hm_getelemcheckbounds Help I hope this can help you achieve what you intend.

    Hi, for beginners I would recommend Practical Aspects of Finite Element Simulation (and other free ebooks from Altair). Practical Finite Element Analysis is another good place to start (here is a preview). There is also a theory manual section in Radioss help. When/if you are ready to dive into depths of FE: The Finite Element Method for Solid and Structural Mechanics. For practical demonstrations I would also recommend the following Youtube channels: Altair University Altair India Student Contest ELEATION By Apoorv Bapat

    Hi, 1. Utility>BC's manager select the BC you want to display and hit Update 2. If the initial energy in the system is low, then it is possible to have large Energy Errors early in a simulation that reduces as energy is added to the system and this is fine. This is because small numerical differences in the energy cause large percentage Energy Errors. Hourglass and contact can also cause energy errors because they are not part of the energy balance equation. To avoid hourglass energy use fully integrated element or underintegrated with physical stabilization (Isolid=12 or 24). That being said, I was not able to correct high energy error in your model, which goes to 99.99% right from the start of the simulation and never reduces. 3. The model you have shared is not suitable for explicit simulation, because of small element size that penalizes time-step. You should remesh the model, paying more attention to minimum element length (check with F10>time). Simulation can be sped up using DT/NODA/CST or Advanced Mass Scaling. Time scaling can also be applied to obtain a quasi-static solution as long as kinetic energy is less than 1% of total energy. If loads, geometry and BC's are symmetric the model can be appropriately reduced. Given the load is applied over 2 second period, there are negligible inertial effects so explicit is not necessary. There are also no geometric, contact or material non-linearities that can only be solved by explicit. Check the remeshed model attached below: ARS-support-A1-v2-Forum_edit4.hm
