  • If you are keen on getting stress results on your beam elements have a look at the below link. You can use your Mecway results to generate what you are looking for https://pypi.org/project/sectionproperties/2.1.2/
  • I have used the "sectionproperties" package. It works very well!!! Highly recommended, it can even read Rhino files if I remember correctly.
  • Not sure if this is possible on Calculix, but I have previously simulated a moving load using truss elements with prestrain applied to them. I had a node with the mass which was assigned a velocity. That node was attached to the boom using truss ele…
  • Random question, is that a pan feeder or something similar?
  • If possible it would be nice to have a tool which adds a mid surface if two surfaces are selected. This may help since most of the lower end CAD software do not have a mid-plane option. Additionally deleting surfaces would also help. Not sure if thi…
  • I am not a fan of IS, it is very difficult to get any sort of technical (theoretical) information on the product. I find that most software designed for structural engineers are developed very poorly and often follow different formulations compared …
  • Hi @disla, this really sounds amazing. I have done this sort of stuff on Strand7, didn't even know that it would be a possibility on Mecway. It would be really nice if you could share a simplified model for the case when you have it up and running.
  • Where can I download the Beta of version 20?
  • I didn't know that Calculix also expanded plates into solid elements also. I assume that there is a really poor mesh over the thickness of the element if Calculix is doing this automatically. It actually makes a lot of sense now regarding the solv…
  • @Sergio I would assume that you need to a decent amount of elements through the thickness of the solid in order to get accurate results using solid elements, am I correct? I was once lazy and used solid elements for some sheet metal on the old 32bi…
  • If you keep the contact and run a nonlinear dynamic the results can be processed to get the natural frequencies. You would need to do this out of Mecway
  • It would be nice if the internal solver could cater to different line element sections as opposed to just general sections, when considering transient analysis. Is this possible?
  • Random question, if one makes the purchase of Alibre Atom, you obviously get a maintenance period. Are you still able to move the license after the maintenance period? Or will it be locked to the installed PC? I assume that as long you have the inst…
  • Hi Sergio, please share a link. when I search I cannot find the black friday special
  • Hi Guys Thanks for the answers. @Victor, would it be possible to have a tool which converts a beam element section defined using the internal solver to a set of plate elements? Thus allowing ease of use when moving from the internal solver to CCX.
  • @barmin, how was your experience with DesignSpark? Is it decent for modelling surfaces?
  • I downloaded and ran the model. I must say this is unbelievably impressive!!! I use a relatively high end FEA package which is very versatile, and it is impossible to develop an analysis model like this that can solve.
  • Hi Victor Would it be possible to get an option to view the nodal element forces for plate and brick elements? With a tool which would sum reactions about a point. For example if one has a beam modelled from plate elements, one could then select no…
  • Thanks for all the comments and assistance! @Victor the Paraview export sounds really amazing. You really have provided an amazing piece of software.
  • Hi Guys What is the purpose of doing a FEA for such a connection? or is this purely academic? I have only done FEA for connections which cannot be designed by hand as it is very time consuming. Personally I would just use a structural code such as…
  • Hi Guys Not sure if this possible as I have not used contact that much on Mecway. Would it be possible to apply contact at the joints of the truss members, this will allow for only compression to transfer. I have done a similar thing on Strand7 wh…
  • The Mecway files are text readable. If you open the file as a text file you can review the manner in which Mecway requires it's data. You can then use VBA in Excel or another programming language to develop a text file in a manner which Mecway can r…
  • If the geometry is simplistic, meaning that it is a basic retaining wall without any curves and/or funny geometry, you can then just model it using 2D using beam elements of unit length. With a little post processing you will be able to get the resu…
  • The displacements just present the mode shape and have to relevance to any actual displacement. Normalized mode shapes can also be used as in an input to some of the transient solvers. Calculix does give the mass participations, this is be found in…
  • Hi Guys, Thanks for all the comments. The epoxy is used on a vibrating screen. I intend on taking measurements using an accelerometer at various locations and using this information to calibrate to a bolted connection and thus I can develop an em…
  • Hi gwillis Can you please show an image or a model as it is difficult to tell what you are aiming for. A cross shape for two bars would have 5 possible locations for bolting which of these should be free to rotate?
  • Thanks for the comments guy!
  • JohnM, thanks for your response. Are you guys generally using brick meshes or surface meshes? I am not sure about Solidworks and Inventor, but FreeCAD cannot create a midsurface from a 3D model. The fixing up of my models usually pertains to develop…
  • Hi Sergio Out of curiosity why didn't you just use beam elements for the model, and design all the structural members and lugs using design codes?
