Hi.. Thanks .

many thanks. Could you please eloboarte. I am new to CFD and thermals. I want to study how the density, heat capacity and thermal conductivity of the components and the temperature of the cooling water effects the temperatures of the machine. Please bear with me if i am asking a very basic things.

Hi .. I am simulating a water jacket cooled induction motor. I solved the simulation for two cases case 1 : cooling water inlet temperature 30 degree Celsius. I this case the outlet water temperature is 31.4 degree Celsius. and the temperature at the area of...

Hi Thanks for the valuable information.

Hi.. I am working on a structural analysis of an alternator under rotational forces( Using Optistruct ). can any one help me in modeling copper winding.Its not possible for me to model all strands and applying contacts. IOs there any any modeling technique for modeling winding for structural...

Thank you

Exactly , I am designing it. But for designing it i have got few documents , But all of them explains the calculation method by considering the component to be isolated as a rigid mass. In my case the component is is a excitation panel (assume a box with number of sensitive electronic components...

Hi I need to select a shock mount for sensitive electronic components for a control panel for naval applications. Can any one share any document , explaining step by step procedure for shockmount selection(preferebly in SI units)

Hello i am using nx nastran 10.when i solve a linear static solution, with out any load , it is getting solved and giving zero displacement results which is correct with a zero load. But when i use nx 9 ,when there is no load in the linear static solution .when u click on solve,it will give a...

What i believe and follow is consistency means if your model is in mm use mm, kg(or tonn) ,and newton(or milli newto or kilo newton) as units. if the model is in inches use inches , lbf. correct me if i am wrong .

HELLO 1.WHAT IS THE PURPOSE SURFACE TO SURFACE CONTACT SIMULATION OBJECT IS AVAILABLE IN 101 (LINEAR STATIC)SOLUTION AS CONTACTS MAKE THE SOLUTION NONLINEAR. 2.WHY PLSOLID IS AVAILABLE IN PHYSICAL PROPERTIES OF 101 SOLUTION AS PLSOLID IS USED FOR HYPER ELASTIC MATERIALS(NONLINEAR MATERIALS)...

Hello everyone I want to create an excitation function for dynamic analysis in nx nastran. Can any body help me in HOW TO CREATE A TIME VS DISPLACEMENT SINE WAVE WITH A SINGLE FREQUENCY AND SINGLE AMPLITUDE.

Hi Thanks for the response I have run normal modes analysis also.No extra rigid body motions found. The problem is I am getting excessive pivot ratios at a particular node as follow...

sorry , By mistake i have exported a wrong .dat file. Suppose if there are no constraints the model should not start solving , the model setup check will give an error saying , there are n constraints in the model. in my case i have given proper boundary conditions (fixed on one end ). Still it...

actuyally the model is of varying thickness one. there is a [roblem with pivot ratios . here i am attaching my .f06 file .and .dat file i have checked the connectivity . every thing is ok. But I cant figure ou what the problem is...

Helo every one i have a sheet metal plate meshed with shell elements. When i solve with proper boundaty conditions , its getting solved and giving all the displacements and rotations zero. can any one please tell what the problem is exactly.

Hello i got the output,shell element thickness output is only available for large strain model. So we have to check large strain in the parameters section of the solution box.

Hello I am not sure, but Check whether you specified the modeling object for Advanced nonlinear(BCTPARAM) in the surface to surface contact dialogue box and check whether you have created the global contact parameters in the solution dialogue box.
