Thank you for the new version. The STEP file path feature is much appreciated.
-
@disla Thank you very much for sharing this very clever trick, I've tried it, fantastic. I am needing to transition from a tet mesh to a structured manual mesh. This method of closing a shell skin should allow me to 3d automesh a transition volume…

Correction: I meant to say Quad4 edges not Tri3 edges

Thank you Victor, I'll try the revolved wedge. Tim
-
That's great, it's all much appreciated
-
Hi Victor, Thank you for the point mass confirmation. Is the *RIGID BODY possible? My top wish for Mecway is to define a *EQUATION statement, one dependent, multiple independent nodes. I define many *EQUATIONs in the CCX custom model definition (ma…

Victor, Ok, thank you for explaining, I'm fine with that. Tim
-
Victor, Thank you for clarifying these points for me, all good news. Tim
-
Victor, Thank you for your comments, I will test the position of Default within the .liml file. The most difficult aspect was that the new elements did not display. Could the logic be as follows? If the new element is connected to an existing mesh t…

Victor, Thank you very much for providing the theory and creating the example; I must now work to gain some understanding of what's happening here; your help is much appreciated. Regards, Tim
-
Victor, thank you for describing the situation regarding angular acceleration. Would the implementation be way down in your enhancements list? next version? In the meantime I am very interested in the two centrifugal force trick, any further info gr…

Thank you Victor, some textbook revision required here.
-
Victor, Thank you for your help with SED, providing formula and example. Much appreciated. Tim
-
Victor, Thank you for the stress tensor links. The radial component is defined as (x*u.x + y*u.y) / sqrt(x^2+y^2) in the manual. My poor transformation skill leads to ur = (u.x^2+u.y^2)^0.5 but this losses the sign (sense) of the displacement where…
-
Sergio, I'm looking at a ring beam so the stresses of interest are on planes that run radially from the axis that passes through the ring centre and is normal to the plane of the ring. I have calculated the transverse shear force, bending moment an…
-
Hi Sergio, Thank you for your suggestion; I was working directly in Mecway but yes see that I could work in CCX and certainly view the results in CGX. I should try to read the .frd with cylindrical results (using *TRANSFORM) back into Mecway. I'm k…
-
Victor, Thank you, the export of node forces will be great. I will try the normal pressure with formula in the meantime. Regards, Tim
-
Victor, Thank you for describing the method that you intend for managing different thermal solutions, I see the benefits over how I've worked to date. I suppose that if I make the first configuration contain all the envisaged thermal & structura…

Great thank you Victor
-
Thank you Victor, Looking forward to using V6
-
Victor, Thank you confirming the route for gap conductance. What are your plans for enhancement of contact definitions in the next Mecway versions? Tim
-
Sergio, that's a really good looking presentation style; I will have to give that a try.
-
Victor, Thank you for your assistance. I am applying loads directly to the mesh for the duration of this job and on the next shell model I will look into whether I can align all of the surface normal directions, within the CAD stage. Tim
-
Victor, The attached 'tank' model is where I have carefully built the Solidworks model so that the plane on which each side is sketched, is facing inwards. In Mecway I select the five geometry internal faces and then use this named selection 'Surfa…
-
Victor, Thank you for clarifying the pressure / traction application method. I am using the STEP file surfaces to apply the pressure loads but I come up against a normal direction problem; some of my pressures are applied to the internal shell faces…
-
Ah, the half shell thickness offset, this is creating a bending moment when the pressures are both applied to the same side of the shell element!
-
Victor, I've attached an example of how I can apply a traction to an inclined shell panel. The intention in this example is to apply a pressure that results in a 1000N reaction that is in-place, i.e. a traction. In this example the Y-direction pres…
-
Victor, Thank you for the guidance, I'll read further.

I would also really like to understand the relationship between the 2% damping that is often quoted for steel structures, and the alpha and beta coefficients used in *MODAL DAMPING. Tim

Hi Victor, thank you
