How do I model and solve the pde for pressure distribution as given in the figure. Everything apart from pressure will be given a numerical value. I have uploaded the model, I need to find the pressure distribution on the thrust pad bearings. 댓글 수: 3 이전 댓글 1개...
sol = pdepe(m,@pdefun,@pdeic,@pdebc,x,t); Below are my code lines, FeCsat is an array of numbers %% Defining the PDE function function [c,f,s] = pdefun(x,t,u,DuDx) c = 1; f = [-v*u]*DuDx; s = ((4*((0.5950*10^-7.667)/2))/0.0169*sqrt(t))-((0.05*u) - ...
Written in this form, you can read off the values of the coefficients c, f, and s. In MATLAB you can code the equations with a function of the form function [c,f,s] = pdefun(x,t,u,dudx) c = 1; f = dudx; s = 0; endIn this case pdefun defines the equation ∂u∂t...
I am trying to solve the following PDE (one-dimension diffusion): with the following boundary condition : I read the documentation here :http://www.mathworks.com/help/matlab/math/partial-differential-equations.html?refresh=true#f1-697925and I saw that it works for ...
hi, all I am trying to use coefficient from PDE to solve helmholtz type partial differential equation. (I know there is helmholtz equation, but both module doesn't working) So, first I am using COMSOL 4.4 with MATLAB, and I follow the instruction as following link to use MATLAB ...
PDE-constrained optimizationPoisson controlCollocation methodIndustry SectorsIT &SoftwareElectronicsEngineeringAerospaceTelecommunicationsIn this article, we apply the theory of meshfree methods to the problem of PDE-constrained optimization. We derive new collocation-type methods to solve the distributed control ...
I am not an expert in MATLAB and I did my best in coding my 5 PDE's using pdepe command but keep getting this massage? Z must be a matrix, not a scalar or vector. My codes are ThemeCopy m = 0; x = linspace(-10,20,200); ...
The unknown PDE solution u is approximated by RBFs in the form of (1). We assume the collocation points are arranged in such a way that the first NI points and the last NB points are in Ω and ∂Ω, respectively. If one collocates at the data centers, the collocation conditions of ...
