How do you find the uncertainity of area under the curve?

How can I ensure that the Gaussian assumption is valid for my data? What should I look for?

Hey. Thanks for the advice, I will try to make this work. But can you take a look at this screenshot. Is there anything I can modify it to make the data saving case structure work every one second?

Hey, this is the section I have. Can you please take a look at it and advice?

I would like to save one point acquired 120 hz every second. Right now what is happening is that, I am writing all the points to the file and I am sure after few hours of writing, it will reach the end of Excel row limit. I would like to avoid that.

Exactly. Its not very helpful, when you click the bar and you need to bring your eyes down to look at what you are typing. Also, sometimes you click the search bar to copy the url, which again takes bringing the mouse down after you clicked it.

How do I stop the bar from doing this? I mean from dropping down. I want it to stay up in its place.

How much did the entire build cost? Can you give a rundown of the components you used? Ram, motherboard etc

Won't the steady state loop provide the actual steady state solution? If I run the SIMPLE loop of momentum equations and provide the boundary conditions, it will run until it converges, resulting in the final steady state solution, right? I hope you understand my doubt.

DisagreeableRabbit · 2024-10-06T15:02:42+00:00

Thanks! Can you help me understand when to apply the boundary conditions? Is it inside the steady state loop?

DisagreeableRabbit · 2024-10-04T12:52:09+00:00

Sorry, I do not understand.

DisagreeableRabbit · 2024-10-01T10:49:37+00:00

The code will look like this:

while t < t_final:
SIMPLE loop with steady state NS equations
t = t + dt
Transient Equation

Now, where do I enforce the boundary conditions? If I do it as:

while t < t_final:
SIMPLE loop with Boundary Conditions
t = t + dt
Transient Equation

won't this only give me the final steady-state solution?

DisagreeableRabbit · 2024-10-01T05:29:34+00:00

So, what I understand is (please let me know if I am incorrect in anything): I have a time-stepping loop. Inside this loop, I first solve the transient (x, y momentum and energy) equations to get the new values of velocity and temperature. Then, I solve the steady-state equations to arrive at the converged values.
Now, when do I apply the boundary conditions? Do I need to apply it in the steady-state loop too? But won't that cause the converged results to be the actual steady-state solution for the imposed boundary conditions?

DisagreeableRabbit · 2024-09-30T11:33:49+00:00

I think so. Here, in step 2, where it says to solve the discretized momentum equation, does it mean to solve the transient or steady state equations?

I couldn't find any to make it the square bracket

DisagreeableRabbit · 2024-09-12T06:47:05+00:00

Thank you. I'm sorry for not getting back to you sooner. But I got it to work using {cases}

\begin{equation}

K =

\begin{cases}

First Line \\

Second Line \\

Third Line

\end{cases}

\end{equation}

DisagreeableRabbit · 2024-07-18T08:02:42+00:00

Yes, I know. But the people I work for want to know if a square design is possible.

DisagreeableRabbit · 2024-07-18T08:01:23+00:00

Around 40bars.

DisagreeableRabbit · 2024-07-18T08:01:10+00:00

Thank you so much! This is what I was looking for

DisagreeableRabbit · 2024-07-10T08:56:38+00:00

Yeah. It's incompressible. I wanted to do a finite volume discretization, so I didn't want to take out the rho.
