    Unsymmetric CG method failed

    Hello guys, I am trying to run the cfd-thermal analysis. My model was working fine until, I changed the specific heat of the fluid and I started getting this error message. "Unsymmetric CG method failed catastrophically" I checked all the boundary conditions and constraints. They seem to be...

    how to create pressure incident wave

    Is there any way to create an incident pressure wave for acoustic analysis in ANSYS? I did notice that in electromagnatic modelling there is an option of creating an incident plane wave.

    Refining Mesh

    I am trying to refine the mesh on the current model. I have some constraints/loads (i.e. FSI, pressure) on the structure and surrounding fluid. But whenever I try to refine the mesh, ANSYS asks me to remove the loads/constraints. I was wondering if there is any way to refine the mesh without...

    Harmonic Analysis Results

    For the harmonic model that I have, I need the solutions as amplitude and phase. Even though I select amplitued and phase in "Analysis Options". The contour plot displays the real and imaginary solutions. my models consists of a 2D cylinder surrounded with air. The pressure loads are applied at...

    how to divide the sphere?

    I am trying to divide the sphere in two parts but having a problem doing it. Here's what I did. - I created a hollow sphere with R1 = 10e-6 and R2=77.5e-6 _ To divide the sphere into two volumes, I created the rectangle area with x1,x2=(77.5e-6,-77.5e-6) and y1,y2= (77.5e-6,-77.5e-6) and...

    How to use Transduecers?

    I'm performing the ultrasound scattering simulations. As a boundary condition I need to create a pulse/plane wave. Since the elements types that I'm using do not have electro magnetic properties, I cant use "Preprocessor>Loads>Define Loads>Apply>Electric>Excitation>Planewav0>Define Wave". But I...

    Incident Plane Wave

    I am trying to model the scattering of biological cell. So far what I have is a solid sphere (cell with elastic properties) inside a hollow sphere (FLUID-Water) with fluid-solid interface and aborption boundary. Technically, this is a fluid-structure coupled acoustic analysis. Only thing I am...
