    Round filllet coordinate for pipeline

    I have 3 known point, with coordinate P1-(X1, Y1, Z1), P2-(X2, Y2, Z2), P3-(X3, Y3, Z3). straight line is draw from P1 to P2, P2 to P3. they are "not" colinear. I would like to fit a round fillet to the conner with a "Known" radius of R, and I would like to know the coordinate of the 2...

    Bug in 6.7.1 (restart file broken)

    Just want to share my experence which I have learn it in a hard way and confirmed with ABAQUS. In ABAQUS version 6.7.1. the restart file will be broken if your analysis do not finish to the end, either by computer crash or manualy force stop the analysis. ABAQUS said this wil be fix in next...

    Loading on pipe ends

    In a full pipe model I belive I can apply tension or compression on pipe ends by using Distributing coupling or pressure at pipe end. However, If I want to model half pipe by taking symmary along the pipe. How would I do the distributing coupling at pipe ends? I tried to do it as I would with...

    Von mises stress above allowable stress in material?

    I have modelled the material as following: *Material, name=steel *Conductivity 45.33, *Elastic 207000., 0.3 *Plastic 423.,0. Why do I have von mises stress of 470MPa using banded plot, and 433MPa for quilt plot? Would't the stress should not pass the highest stress then the material? Doing...

    Mesh size verification

    I have read a document that stated: the mesh density of the FEA shall be sufficiently fine to allow accurate resolution of stress and strain levels in critical regions of the structure, and shall be verified using the guildlines provide in th "NAFEMS Finite Element Primer" Does anyone know what...

    beam normals warning

    I have the following warning in the .msg, What do they mean and how can I check this in the model? How its going to effect my results? many thanks "For 2 beam elements either the average curvature about the local 1-direction differs by more than 0.1 degrees per unit length as compared to the...

    Units Confusion

    I am having some unexpected results, Can someone check my units please as I always have confusion in them. Units: N,mm Length = mm Force = N Mass = Tonne (1.0E3kg) Time = second stress = MPa (N/mm^2) Energy = J (J) Density = Tonne/mm^3 Conductivity = J/(s.mm.C) Specific Heat = J/(Tonne.C) and...

    Uncoupled heat transfer analysis

    I have a pipe that the product inside is 60oC. half of the pipe is in the water which is 4oC. and half in in the air which is 22oC. How should I apply the boundary condition to the 3 surface of the pipe (inside pipe, outer pipe in water, outer pipe in air)? in order to output the temperture...

    Max principal Srain does not match Principal stress

    I have a model that uses material of steel with yield around 400Mpa. It is base on Ramberg Osgood material behaviour where the total stain is 0.5% at yield I get the following results. Mises = 370Mpa Max Principal stress = 430Mpa Max. Principal strain = 0.25% The question is if my Max...

    Removing *equation Constraint

    If I have use *equation constraint in Step 1 to control node Set with node set B. Is that possible to remove this constaint in step 2, so that I can fix node set A but allowing node set B to move free?

    Units

    In ABAQUS, if I use m as length and MPa as the unit of Stress. what will be the unit of Force and density please?
