The resulting assembly was in "asm" format . When i import this assembly into ANSYS it gets imported as multiple volumes . How to import it as a single volume ?

Can I use fracture mechanics module in Ansys for a notch to get stress intensity factor and J integral? (notch is 6 mm wide, 25 mm in length). If not, do I have to create a crack, do I have to create a line to model it?

For the thin walled pressure vessels I'm designing this works well.</p> <p>In Workbench I can create a thin shell in the modeler by selecting thin/shell during extrusion. This is then meshed using 3D elements which are either very skewed or overnumerous.</p> <p>Alternatively I can create a zero thickness shell in the modeler by extruding a line. The mesher will mesh this, but I can find nowhere to specify a thickness. When I try and solve the model with some forces and pressures the solver cannot run as there is no volume specified.</p> <p>I am sure I'm missing something very simple, for instance a menu that allows the element type to be changed to shell. If anyone knows how to model shells in Workbench please help. </p> http://www.FEA-Forums.com/topic/340#post-446 Tue, 26 Jul 2011 09:56:12 +0000 kidari 446@http://www.FEA-Forums.com/ <p>Hello to all ANSYS experts in this forum.<br /> Happy to join the group and hope to learn lots about ANSYS.</p> <p>my goal is to have a conformal meshes on surface bodies.</p> <p>1.

But I haven't still manage to create a correct model.<br /> I want to find strenght of K joint with tubular section by FEM analysis ( Ansys). So the point is not how to create the model how to mesh it.<br /> I already know what is the strenght of joint by using some formulas given by CIDECT. When I want to model an example given in this book for a correct K joint.<br /> I always found a stress ( Von -Mises) higher than the yield stress of the material. That means that the joint is not correct.<br /> When I decrease the size of element, the stress is decreasing that seems really normal, But when I refine the mesh around the connection part of the joint. The stress at this part increases, don't seems stop to a correct value.<br /> Any idea what is my mistake to model this K Joint?<br /> Really appreciate if someone can give me a hand. </p> <p>Charles </p> http://www.FEA-Forums.com/topic/323#post-426 Sun, 12 Jun 2011 01:43:03 +0000 zhiling0229 426@http://www.FEA-Forums.com/ <p>Hi everone,</p> <p>I'm kind of new to Ansys.</p> <p>I'm using ANSYS 12.1 and currently when i use the steady state thermal analysis on two geometries I observed that the heat does not conduct to the other geometry even though the connection already show that they are bonded.</p> <p>Need help. </p> http://www.FEA-Forums.com/topic/322#post-425 Fri, 10 Jun 2011 02:14:55 +0000 Jiri 425@http://www.FEA-Forums.com/ <p>Hello everyone,</p> <p>I would like to ask a question corcerning a posibility to simulate drying process of a fiber material (i.e cotton towel). I am doing my PhD. and investigate this possibility in ANSYS Fluent 13.0</p> <p>At the present I set the simulation this way:</p> <p>1. geometry - there is a pipe and porous volume inside. Hot air (mass flow) is defined at the inlet. Porous volume should have represented i.e. cotton towel.<br /> 2. I used Multiphase-Eulerian model, 3 phases (air, water, vapor); there is mass transfer-evaporation set in phases interaction dialog box. It looks that evaporation works quite well.<br /> 3. water is PATCHed in porous volume cell zone as volume fraction after initialization</p> <p>By this steps i would want simulate drying but I am not sure whether I can use porous volume (porous zone) for this. Problem occures when hot air is passing through porous zone - than the water escapes this porous zone after short time (circa 0.8 sec). Simulation is set as transient (time step 0,001sec). Porous coeficients was set the way reflecting real test (pressure drop in the pipe).</p> <p>Has anybode some information about possibilities to simulate this case. i think that main goal is find out how to "hold" water phase in porous zone longer time and evaporate it- means do not allow to escape it immediately with passing air.</p> <p>Unfortunatelly I can not use Ansys customer portal to ask the experts because our university doesn´t have maintenance.</p> <p>Thanks a lot for any information. </p> http://www.FEA-Forums.com/topic/30#post-423 Thu, 09 Jun 2011 11:17:35 +0000 alanotero10 423@http://www.FEA-Forums.com/ <p>Same problem for me, both ones. I'm using Ansys 13 and after 3-4 iterations i got next message "unknown parameter name = _Z3 found,a value of 7.88860905E-31 will b used." what does it means and how can i fix it. And also, how can i maximize the objective function instead of the minimize (default)? </p>
