Dear all, I have created a part consisting of 2 perpendicular shell surfaces. I partitioned the part using datum plane (through both cells). I want to use the part in a heat transfer analysis. When submitting the job I get the error Underlying element X instance Y can only have spos or sneg...

Hello, Referring to stress and strain of reinforcement in shell elements. After I toggle on to INCLUDE the rebar in the FIELD OUTPUT I have two extra SP in the output graph. My shell has 13 integration points. Before including rebar stress in the FIELD OUTPUT I was able to see the stresses at...

Hello, I have managed the rebar issue but if you have any information regarding SF, please help Thanks

Dear all, I am modeling a beam element to check the SF obtained for different position of the reference line. First I have the reference line of the CS in the centroid. If I apply a longitudinal force, I obtain SF1 egual to the force corresponding to yield stress. If I define the reference line...

Dear all, I have modeled 3 elements which intersect in one point. the link between them is a connector (join- translation DOF). How can I obtain the section force of an element which belongs to the connection? When I try to use probe values it says "no value". Thank you in advance,

Thank you for your kind help

Dear Mauce52, By beam element I meant to say "wire" element for which the available cross-section library is presented in "Analysis User's manual". It will be very helpful if you can provide any references. Thank you

Thank you very much! It cleared things a little bit until I was comparing two cases: constant temperature through section and gradient through section. The attached picture shows the points considered by Abaqus. In the picture I have inserted some charts. My question is why for the constant...

Hello all, I have some problems understanding the meaning of the two notions NT and TEMP. I am analysing a linear element (wire) for which I defined a gradient. If I want to check the results the two variables, NT and TEMP for the same node, are quite different. Can anyone enlighten me...

Hi everyone, Is it possible to model a beam element with 2 different materials? For example a steel tube filed with concrete. Thank you, Best regards

Dear Corus,dear all, I am analyzing the same structure described above, concrete slab with steel beams. I have performed a sequentially coupled thermal analysis of the slab (with 7 integration points) and then a mechanical analysis. I was checking the temperatures given by the thermal...

Hello everybody, Dear Corus, Thank you for your advice. I works faster now with sequentially analysis. I have modeled the composite slab using shell elements. I have tied the beam to the slab. The analysis stopped due to over stress in the beam due to compression ( the beam is expanding more...

Hello, So, after running the Standard model again without structural loading, only with thermal conditions, the model stops at 600s. I obseerved that the beam is expanding (at the bottom flange)more than 12mm while the slab expands 1mm. Do you think this can be the cause of "in-convergence"...

Thank you Corus for reply! For both Standard and Explicit I have used: "static, general" analysis for the first step and "coupled temperature-displacement" analysis for the second step. For the Standard part the error is: "Time increment required is less than the minimum specified" For the...

Dear All, I am trying to model a fiber reinforced concrete slab on steel beams. I have applied the load in the first step and applied thermal conditions (convection and radiation) in the second step. The analysis reached 400seconds (tops) ( I was expecting 7000s). I have modeled the structure...

THanks for the reply. The above "unknowns" are input data for temperature load (nonuniform) on elements. (in APDL)

Hi I want to add a temperature on one face of a BEAM24 element. Does anyone know how to do that? What do the following mean: STLOC starting location N ____ VAL1 Temperature at location N ____ VAL2 Temperature at location N+1 _____ Val3 Temperature at location N+2 _____ VAL4...

Thank you for guidance I am pretty new in Ansys and I have to figure it out how to do that. Moreover I have to figure out how to use Beam24 element. If you have any advice or references where I can see the steps for input files, please let me know. If I will succed with the model I will tell...

Hello Can anyone help me to make a thermal analysis for a cross section and afterward make a structural analysis of a beam, taking into consideration the temperature distribution from the thermal analysis? Thank you Bothul

Thank you n3l3 I hope I will
