Hello everyone, As i am working on a composite optimization in optistruct, I have a model on which i have two load cases at the moment, I will try to state the problem in briefly, 1.My aim is to get the displacement at a range between 15 to 18mm in one load case and in the second load case which is Non-linear it should be below 40mm. 2. I have to consider the composite failure as well in my model which is PUCK failure. 3. I am working with the free size, size and shuffle optimization before doing the optimization i run the basis analysis of my model and i am getting the displacement for the first load case is around 14mm and for the second one is 38mm. 4. I have tried with so many possibilities during the optimization but didnt get the solution. I kept response as compliance, static displacement, and composite failure. I am bit confused whether this responses are correct for my case or not. 5. Constraints i give for displacement. Objective is to minimiese compliance. I look forward for your reply it would be very helpful if someone give your advice on this concern.

Hello, Does anybody know how to perform stress linearization across a the thickness of a pressure vessel in Hyperview? I am a Hyperworks 12 user. Thanks in advance, Best Regards, Gabriele -
Hello, Does anybody know how to calculate the percentage error in the energy norm for a selected set of elements? Ansys provides a tool called SEPC (obtained from the PRERR command). I am interested on how to do it via Optistruct solver. I am a Hyperworks 12 user. Thanks in advance, Best Regards, Gabriele

Hello All, I want to analysis a full solid cylinder and i want to reduce the time of the run. Someone suggested to me that I may find an option about analysis only one vertical section of the cylinder and the tool itself will make a revolve and generalize the result as if it was a 3D analysis. Does anyone are familiar with this option? is there something like that in Hyperworks? thanks

Hello, I have one assembly where, coolant is flowing (with some pressure / velocity) through a hole drawn in the solid heated plate, Can we calculate the heat transfer from the heated plate and the coolant(i.e. cooling rate of the heated plate) cfd1.bmp -
Hello Sir, (This question arises from the development of the draw surface) If process has sequence as follows: 1. Blanking process 2. First Draw process 3. OD trimming process 4. Re-strike process ....as in one-step we get the flat blank from any draw/forming tool, as the same process can we get the blank input (blank with draw shape) for the re-strike tool from the first draw tool (i.e. input blank for re-strike based upon first draw operation) Please share if any another process sequence / video explaining regarding the same.

Hi I am doing a simple stress analysis because temperature rise. I have given TREF in MAT1 and TEMP applied by TEMP_LOAD. I am getting high stresses in a fillet area ,which is the expected location. But the value keep on increasing with more refinement in area ...(4 , 8 , 12 elements on fillet,fillet radius is 0.5 mm) So please help me in which values i have to take ...(number of elements on fillet)

Hello All, I am using radioss to analysis cylinder. I am applying Concentrated load and this load does not have any effect and I do not find any stresses on the part in the Hyperview. I made curve (x= 0,10,25,250 & Y=0,0,0.02, 0.02) and apply it to a node in the center. Kindly, find the file attached below. full cylind.mvw full cylind.hm

how to get > streamlines > spheres contour in Acufieldview .I have attached 1 image

Good morning ladies and gentlemen. My name is Yogi Adi Wijaya, and I am an academic students from Bandung, Indonesia. I have tried a simulation about T-joint plate test using Quasi-Static loading (using RADIOSS). But, the result in HyperView show that the structure is not broken as in experimental testing (similar with tensile test). How could this happen? I need answers from all of you, and I hope that this problem could be solved. Thank you very much. Regards, Yogi Adi Wijaya

I am working on a component where I have to constrain one end of the model only in Rotational. . and those constraints should be locally defined( planar constrain). Pls find the attached image. The black highlighted face area has to get constrained to that local plane only in rotational. pls guide in this regard, Thanks, Nagaraj

Hi Bro Good evening. I have to find the insertion force and the removal force. Since the geometry is complex hexa mesh is very difficult so I have to go with tetra mesh. I have tried the enforced displacement lateral force analysis method where the results are not correct. The problem description is as follow. To find out the insertion force. (<90 N MAX) To find out removal force. (F=90N MIN and 150N MAX) Since there is no tutorial for this kind of analysis. Can you explain me what I have to do next. Thanks in advance...

Hi, How to convert Acusolve .log file to .h3d file format. If i direct try to import .log file in hyper view, its getting crashed. Could anyone please share me the procedure. Thanks, Venkatesh -
hello sir, sir i have a problem, sir i am solving a problem in which a rigid ball is dropped on a steel plate,ball contain 2d mesh on its surface and 1d rigid element,initial velocity is applied on the centre node of rigid, deformation only occur in plate not in ball. sir i have problem in creating interface,please tell me how to create interface of type 7,on which component i have to create contact surface

hello sir, sir i have a problem, sir i am solving a problem in which i have a spherical ball on the surface of ball i have done 2d meshing and i have created 1g rigid element in that sphere,now i am assigning some velocity to that centre node of rigid element ,but still the ball is not moving from its position.please tell me how to do this .

Good afernoon ladies and gentlemen. I am Yogi, a students from Indonesia. I have a problem to using local coordinate, using RADIOSS software. The problem begin, when I am finished input the new 'local coordinate' (system), and inputed the imposed (VELOCITY) using Y-Direction. How, I change the direction of IMPVEL from Y - direction at global coordinate, became to Y - direction at local coordinate. Please hel me, to sloved this problem. Thank you. Regards, Yogi Adi Wijaya
