Hey, did you get how to do it?

In the matlab script the Array T is the temperature at nodes. T[0] is temperature at zeroth node... Initially temperature at all nodes is zero except at end nodes., Where it is 100. As time progresses the T is updated. For giving 25 deg as initial condition put T[2:end-1]=25 The above line should be added after the line, "T=zeros(1,nx) ;" in the script. ;

The source term add Just one more line in the code

Thank you.

This equation models the physical phenomenon of diffusion, I mean spreading of a particular parameter (dependent variable) from higher concentration zones to lower concentration zone. Here I took an example of heat Diffusion,the parameter is temperature. We can also model diffusion of ink in water, then the parameter will be concentration of ink.

See 3:53

Yes I do work for pay. It depends on the kind of work, pay and time schedules.

Thank you. This equation is a generalized 1D diffusion equation: (du/dt)=k* (d2u/dx2) Heat equation is also a Diffusion equation. So you can use the same Numerical Strategy as explained in this video. You need to modify the Matlab Script so that the initial conditions, Coefficient - "k" , and the end conditions are implemented as per the given data.

Hi, I have earlier developed a python tool named Py-NAT. It computes the ship hull hydrostatics and stability parameters like GZ curve. May be that script can help you to understand how to compute sectional area for multiple frames. The script is availabe for public through a GitHub Repositiory. The complete script is available at here: github.com/praveen-kch/Py-NAT You can find the demo video on how to use the tool at here : th-cam.com/video/MUr9g9oT8bM/w-d-xo.html Happy that this tutorail was useful. Inorder to compute section area of multiple sections you need to first have an input file that contains offsets of all sections. Then you can read offsets from it and segregate them station wise. To compute section area for each station curve, you need to loop the techniques mentioned in this tutorial. Please go throught that PyNAT script, to understand how multiple sections were dealt.
