## Geometrie für jeder Knote

ich habe ein statisch FEM Analysis bei Creo ausgeführt. Creo erzeugt beim FEM Analysis einige Datei, die ich brauche zum weiter Bearbeitung, dazu gehört z.B. study/Analysis/study.s## und study/Analysis/study.neu.

Was ich genau eilig brauche und nicht finden konnte ist die Geometrie von jeder Knote. d.h. Knote-Nummer w.r.t. Geometrie (Querschnitt, Flächenmoment 2. Grades Iy und Ix, Axial Wiederstandsmoment Wy und Wz, Statisch Moment S, usw).

Wie können Sie uns helfen?

Andere Frage: Wie kann mann die Knoten Nummern anzeigen (Wie die Punkenummern)?

Danke.

Hi,

Does this help?

Regards

Document Details - TPI 141678

General information about h-nodes in the neutral file (ascii format), orientation and order of the nodes.

##### Resolution

See http://www.ptc.com/cs/cs_24/howto/mst1283/mst1283.htm for detailed info.

Q: It is possible to find which nodes belongs to a certain element (tetra, brick or wedge) ?
A: Yes. In the output.spec file, look in the .neu section. Listed in this section are the h-nodes, and h-elements. The h-elements are the
subdivisions of the p-elements. (Triangle p-elements are subdivided into triangle h-elements, etc.) The number of h-nodes and h-elements
in a p-element for a given analysis depend on the user-set plotting grid number for that analysis.

Q:-What is the element shape and which nodes in which order belongs to a certain element?
A: You can determine the shape of an element from the number of edges (iej) of that element. In the h-elements section, h-nodes

of each h-element are listed in order. In the h-nodes section, the nodes of the p-element that the h-node belongs to are listed.

Hello Obay, Did the document, that Charles linked, help you? It is an old document, but basically the information should still be valid. Accessing this kind of information is not easy, because the idea with (current) Mechanica is to display the information in the solid model and not care about single element or nodes in the background. While I can imagine use cases, where you still need to access information about a certain node, in most cases there are easier methods that can be used. For example, if values at a certain point in the model are needed, you do not need to identify the element at this point. You can define a point at the desired location and define measures at this point. Then the analysis will report those measures in the results. Maximum values are available as measures/results by default. Gunter P.S. for best chances to get answers, use English language
