P.S. Other problem. Launching inp file (the attached one) from Mecway you receive a wrong message error. Launching inp from SCITE (same CCX version) there is no problem. Also opening frd file with Mecway you will have the correct postprocessing. See…

During heating cycle the plate is unladed. The lifting cycle is short (5 10 min) so I exclude creep. Hook is a commercial component by Crosby and it doesn't undergoes heating cycle. Euronorm give a 33 MPa Yiled stress for S355 at 830°C

Plate-hook assembly

I don't know if will be more simple but an option to work unitless?
-
You can try with CCX using "compression only material". Is thinked to simulate concrete. See manual With internal Mecway solver I don't know Regards
-
Yes....Select all elements and choose Elastic Support under "Loads and Constraints" tree. Runs only with internal solver...I think. Picture shows a plate loaded with a pressure of 1KPa (1000 N/m2) and an elastic support 1000 Pa/mm. Uniform vertical…

OK! I have understand your priority but I have another point of view because I work every day not for me but for third party. So inp file is a foundamental part of the technical file with the calculation reports because it contains all the informati…

Will remain the problem about *CLOAD. So two different strategies could cause confusion. PS Maybe is not always simple to create the same algorithm for two different solvers. inp file generated by Mecway is often difficult to manipulate manually. H…

Here the solution inverting loads sequence and the right solution
-
OK! Is not a bug is the same principle applied by ABAQUS. This happens also creating 2 or more steps. Same load applied to the same entity is replaced with the new load, also selecting OP=MOD (As a default) Attached picture explain the principle S…

Is it possible to have an example that shows clearly wrong results in strucrural field? Regards
-
I have to try this case with Mecway but I saw that Mecway writes combination of *DLOAD and *Amplitude in a wrong way. In fact the reference value of a pressure or a gravity is 1 and the amplitude value is the reference value. (are inverted) Maybe co…

This proredure is the oldest, I think. Is based only over thermal expansion linear equation. No trial and error method is necessary with beam elements but only calcolous of DeltaT
-
About steel structures and to design or to investigate bolted joints I don't model the screw and nut but I consider the screw as a beam. To link the beam to the plate is possible to use rigid body elements and to simulate pre-tension is possible to …
-
If you want to model joints on FEA environment you have to build different bodies. Is better to use step file. I don't use autocad for this pourpose but I think that isn't the best solution. As Sergio wrote there are many CAD software. If you are s…

IGES is a surface format and contains no solid information. In some FEA is possible to build volume from igs closed surfaces. I think that is a feature of the software that Mecway hasn't. On Salome platform sometimes there are issue importing igs b…
-
You can import dxf into 3D cad and built 3 surfaces. After that you save as step or iges Regards
-
Using CGX as post processor you will have also vMises and principal stresses for ZZS improved stress. Mecway shows only the stress tensor
-
There are two error estimators on CCX solver (see manual) but one of them considers stress difference between the integration points and the nodes (gradient estimator) the second defines an "improved stress" still based on stress at the integration…

In CGX is possible with command "send". To export deformed mesh in abaqus format (inp) the command is -send all abq -

Obviuosly reaction forces are excluded because force summation must be extended to the mesh nodes. I called it "volume integral" because in Mecway has this name but is simply a summation of nodal values when is applied to "forc". Actual volume inte…
-
Could be useful also to separate integral extended to all volume mesh between nodal forces and acceleration forces and separates them for each load case. Now volume integral function takes data form frd file Other question: I saw that Mway by defa…

With *Rigid Body card you can find a solution. All surface nodes partecipates to rigid body There is a difference of stresses and deformations respect *MPC plane
-
Follow CCX forum because M. Kraska is studing this kind of input card. So I think that will be more clear

I use Scite as a editor. This editor prepared by J. Baylor has the integration with CCX and CGX. So you can launch the pre-solver-post directly from the text editor
-
Could be placed also near other functions under Mesh Tools. For example near "Change element shape" which runs also with orphan meshes. There is another aspect. Working with configuration if RIE is activated you will have for all studies RI elements…
-
CCX doesn't has tet with reduced integration. But the problem can be extended also to linear and quadratic elements. For example for contact problems with deformable bodies are generally recommended linear elements instead second order elements.(no…

If can help you this version of CCX runs: http://www.calculixforwin.com/ Regards
