haiz, adina, you are too powerful.

COMSOL material properties study

So today i review the different material properties like ogden, yeoh, all if need input to comsol , it should be in polynomial form.
for this the clearer advantage has been on the ansys and adina, since they possess more advantage and easy user interface on it.

Homework #4: Nonlinear Elastic Constitutive Models

large deformation in comsol

http://www.engin.umich.edu/class/bme456/largedef/largedef.htm

large deformation hyperelastic curve, thank you.

In this section we will only give a brief introduction to nonlinear elastic materials under large deformations, materials more generally known as hyperelastic. Many soft tissues under cyclic loading may be represented as hyperelastic materials, in a from referred to as pseudo-elastic materials. The stress-strain curve of hyperelastic materials is shown below:



Notice that the stress and strain quantities used are the 2nd Piola Kirchoff stress and the Green-Lagrange strain tensor. This serves as a reminder that to be consistent we have to derive the constitutive equations in terms of these quantities.

Next, we recall that any elastic material may be represented by a strain energy function. For Hookean (linear) elastic materials this takes the following form:

how to change google country setting

I use Windows® Vista® and Internet Explorer 8.

I usually get redirected to http://www.google.co.nz

However, typing "/ncr" after the address takes me to that site with no redirection

eg:

http://www.google.com/ncr = google.com
http://www.google.co.uk/ncr = google.co.uk

Should be the same for other countries.

understand ALE

Finally understand what is spatial and material in ALE in comsol.

spatial means you do not move with the flow, so when flow move, measured from you, you will get a displacement.

material which move with the flow, measurement from you will always zero, since you move with the flow.

O.K.
so i decide to use CFX +ansys i need to master it in 3 days.

else i will be fired.

so fluent+ansys cannot do two way,
so i use cfx +ansys according to link

sad to say it is only has it in ansys 13

comsol, although you are good, but sorry, i have not time to tune your solver to get the perfect results.

I would like to have tea time with you, so we can chat a lot, but wait me become professor la.

UDF in fluent

UDF in fluent
http://202.118.250.111:8080/fluent/Fluent60_help/html/udf/node15.htm
1.7 A Step-by-Step UDF Example

There are seven basic steps you should follow to code a UDF and use it effectively in your FLUENT model:

1.
Define your problem.
2.
Create a C source code file.
3.
Start FLUENT and read in or set up the case file.
4.
Compile or interpret the C source code.
5.
Activate the UDF in FLUENT.
6.
Run the calculation.
7.
Analyze the numerical solution and compare to expected results.
To begin the process, you'll need to define the problem you wish to solve using a UDF (Step 1). For example, suppose you want to use a UDF to define a customized boundary profile for your problem. You will first need to define the set of mathematical equation(s) that describe the profile.

Next you will need to translate the mathematical equations (conceptual design) into a function written in C (Step 2). You can do this using any text editor. Save the file with a .c suffix (e.g., velocity_profile.c) in your working directory.

Once you have written your C function, you are ready to start FLUENT and read in or set up your case file (Step 3). You will then need to interpret, compile, and debug your C source code (Step 4), and then activate your function in FLUENT (Step 5). Finally you'll run the calculation (Step 6), analyze the results from your simulation, and compare them to expected results (Step 7). You may loop through this entire process more than once, depending on the results of your analysis. Follow the step-by-step process in the sections below to see how this is done.

Step 1: Defining Your Problem

The first step in generating and using a UDF in your FLUENT model involves defining your model equations.

Consider the turbine vane illustrated in Figure 1.7.1. An unstructured grid is used to model the flow field surrounding the vane. The domain extends from a periodic boundary on the bottom to an identical one on the top, a velocity inlet on the left, and a pressure outlet on the right.

ADINA的问题

百思的解法


最近做了Adina自适应网格及流固耦合的例子（汽车防抱死系统ABS的例子），但是总是出现问题，在进行FSI--Start计算时，提示下面的信息，请问各位高手有没遇到？具体怎么解决呢？


自适应网格分析不能与FCBI单元、自动时间步长、自动内存分配、单元生死，同时使用,
遇到你这个问题可能是你在最后运行求解器求解的时候，选择了automatic，就是设置内存分配那， 还有必须要将MRAM(Maximum Memory for Solution)的值设成0才不出错
