    Okay, it kind of got solved. For everyone who has thr same issue. The System or the Mateial orientation dialog does NOT work for this. (2017.2) However you can create a coordinate system und put it into the property as CORDM. Select "USER" and choose the coordinate system. The materila will orient itself around the X-axis.

    1. The idea is to use the 2D mesh to impose a mesh pattern on hexa mesh. If you want a specific mesh pattern in the through-thickness direction you can also 2D mesh the sides and use nodes or elements as guides (elems to drag/match, along geom). Note that imposing mesh patterns in 2 directions requires well thought out meshing plan as it needs to be 2 directionally mappable. Maybe you will find videos on solid map helpful . 2. surf geom in the case of provided screenshot can be set to none, because it is already defined by elems to drag. Select the surface opposite to the 2D mesh as dest geom. Please hit the like button on useful tips

    Hello @John1989 The FDTD solver currently only supports wire ports and edge ports, so you could use a pin feed to excite the waveguide if you want to solve it with the FDTD. You can refer to Example A-11 in the Feko Example Guide: The model that uses a pin feed to excite the horn antenna can be switched to and solved with the FDTD. It is on the development roadmap to support waveguide ports for the FDTD solver. If this is of importance to you, or if you would like to be informed when it is supported, please request this through the official support channels - see Altair Connect for support contact details or to create a support request. Kind regards Madelé

    I believe you have some modelling inconsistency in your model. Upper arm thickness coincide with parte cima. Define contact between puxator and upper arm or honeycomb.Try all with freeze contact. Not sure about the graph.Is that Displacement vs Force graph? In above shared screenshot force magnitude is 3000 however in shared file it is 2500. Can you also share .out file of the run?

    Hi Bidisha From your description I assume that you would like to extract the multi-port Z-parameters. (Note that the "MoM Matrix" solved during the Method of Moments solution in Feko is also known as the "Impedance matrix" as the elements of this matrix have the the same units and impedance.) To extract the Z-parameters you should request S-parameters in CADFEKO and then, after the simulation has completed, in POSTFEKO use the Export -> Touchstone option. Under the Touchstone export dialog there is an option to select the "Network parameter type" for the export. There you should select "Z (impedance parameters)" to then export the data to a Touchstone file. Kind regards, Johan H

    Hi albertolazzeri, By looking at these images, i think you don't need inner sphere and those extended cylinders. What ever you have meshed, only those components are enough. and i also see that you have not assigned properties to the components. Make sure you assign proper properties to the components and then run the optimization. Thank you

    Hi This is possible and is exactly what time analysis in POSTFEKO does. The analysis is based on FFT/IFFT and thus the signal is inherently periodic (you can't avoid it).

    Hi Pablo I I hope you have done 2D tria mesh using Automesh. For doing an volume tetra mesh, the mesh should be an enclosed volume ie; No free edges. Try fixing the free edges and check for equivalence. Go to Tools > edges and check for free edges and equivalence nodes if any If that doesn't work, share your model please

    Hi @Intan Use Minimize Weighted Compliance for Constrained Volume OptiStruct provides the response type WCOMP, weighted compliance, to be defined on the DRESP1 card. In addition, you need to define the weight factors for each load case included in the weighted compliance function. Note that both the objective and constraint are global quantities (not specific to any single load case) and thus the DESOBJ and DESGLB statements occur before the load case declarations.

    Hello Mrt, This is mostly unanswerable in a forum without the model and detailed information. Here some hints: If you have a lot of geometry, then check the geometry refinements level (Options->Graphics->Refinement Level) and set it to 1 Be sure to shade the complete (geometry) model at the beginning of the work, this will tessellates the geometry. There were already bugs that depended only on the representation of the geometry. Sometimes internally there are extremely many geometrical support points & lines, try the following: Use the Menu "Geometry->Geom Match Topology" tool, use your global geometry tolerance and run This will rebuild the geometry based on the current interpretation and fix a lot of geometry errors If you have really big models, don't use the advanced remesh topology revision option Instead, set "keep mesh" (Options->Mesh->Topology Revision->Keep Mesh), this will keep the existing mesh Otherwise Hypermesh will do crazy checks and remesh operations. Always check the geometry cleanup tolerance, global element size and node tolerance (Options->...) Avoid too small values Best Regards, Mario

    Sorry for the late reply. Just saw this open question. The MetaCurve will eventually be completely replaced by the Blend Curve as we add more and more features and options to it. As a result you will be able to achieve what you are looking for. And just some additional information regarding Class A surfacing. There is generally a lot of confusion about what what it is, what it means, and how to achieve it. There are "A" surfaces and "B" surfaces. "A" surfaces just means the visible/aesthetic side of the model, and "B" surfaces are the side of the model you can't see. Take a computer mouse for example: The exterior surfaces that you can see and touch are all "A" side surfaces, whereas the inside faces of those pieces are all "B" side surfaces. The confusion comes in when you start trying to define mathematically what Class A means. For every company and product the definition can be different. For some the definition can be as simple as tangential (G1) continuity as their minimum requirement, where others may require a minimum of curvature continuous (G2), or curvature continuous (G3). These are all technically Class A surfaces, but due to the automotive influence in the design culture most people associate Class A with G2 continuity or higher. But you also have to keep in mind that the higher the level of continuity the higher the chances are to introduce "wavy" surfaces because the modeler has to manage more and more points and their relationships to each other. So just because a surface is mathematically G3 doesn't necessarily mean it is the desired shape. There are a lot of things that I could get into on this, but I will leave it here for now. So can Evolve be used for Class A surfacing? Absolutely. We have customers all over the world doing this on a whole range of products. Our tools such as Loft, Sweep, Patch, Round, etc...all have options for G2 continuity. The only exception for Class A surfacing with Evolve would be automotive exterior stamped sheet-metal, which is a very special case where additional tools and control are needed and the Class A definition requirements are much higher. Hope that helps.

    Class A surfacing is a methodology and modeling technique. Evolve contains some concepts of class A modeling like curvature continuity but is not the ideal tool for creating flawless surfaces, like those you see on automobiles. The inherent quality of class A surface is its ideal CV distribution. Certain tools in Evolve are based on parasolid(same engine as solidWorks) and deliver undesired CV distribution that can later be partially redistributed. Evolve has construction history, that makes it hard to redistribute points while maintaining dependencies. Most programs like Alias, leader in Class A surfacing, requires you to delete the history before manual manipulation of CVs. However, the nomenclature is slightly flawed. Everyone knows that to achieve a class A surface, the underlying curve must be of the highest quality. Therefore, your curves must contain the least number of CV's and show smooth curvature. See image attached. If you use the top curve to create surfaces, the output will be low quality. The bottom curve has a very close shape but with better CV distribution. Hence, while creating curves, use the curve plot tool - shortcut -SHFT+CTRL(CMD)+P and check the quality of the curve. For product design, class A surfacing is not a mandate, unless you are talking about Apple, that is very particular on surface quality. You can achieve good surface quality in Evolve at the expense of time.
