Hello Everyone,

im working on a Pulsed Laser Deposition setup. In this setup, a laser shoots (at a variable rate) on a target material (the rectangle shaped object at the bottom), that is then deposited (in some kind of profile, as indicated by the transparent cone) on the material on the opposite side of the target. The material on which i deposit is a tape wound around a cylinder, which is rotating at a variable rate.

In addition, the position of the target can be moved along the cylinders main axis.

The image below was created in Fusion360, to illustrate the system. Now I would like to write a code that simulates my deposition process, to predict how much material was deposited at which point of the tape.

Can someone suggest me some good starting points? Do you know libraries or programs (other programming languages are okay) suitable for this job? While I could try programming the system, I am seeking for a way to visualize the process at the same time to have a visual feedback of my calculations, as the parameters may be changed programatically during runtime.

Best Regards

MrHTSC

I am trying to decide learning either Simul8 or Simio for conducting a simulation on systems. Which one of these 2 softwares will be the least demanding on my laptop.

Any other alternatives that are easy to learn and translate ideas quicker and get high level data to explore whether certain projects are worth considering for further analysis.

Hi everyone. I am receiving this error every time my simulation run is completed and i click to see the results. I am performing 200 number of replication. Would be grateful if anyone could help. thanks

I've created code in python to simulate particles and first the goal was to obtain brownian motion, meaning a plot of mean square displacement versus time gives a straight line. However I'm getting an exponent of 1.07 rather than 1.00. Meaning not straight. It is consistent even when I increase run time, change particle size, space size, velocity. I'm not sure what it could be, because when I look at a visualization of my simulation the particles behave completely normal. Any ideas?

Does anyone know how to simulate stock levels in Simul8? I'm essentially trying to model the kitchen of a fast food outlet. I want to set a stock level for fries. When this level falls below a certain limit, I want a new activity 'peeling and cutting potatoes' to become active. In this circumstance I also need one member of staff to switch from a floating resource to a dedicated resource for this activity, until the stock level is replenished to a required threshold. Any help would be much appreciated.

Ok so to explain my sim it’s for manufacturing, so multiple entities(parts) come in and all finish at one robot, I figured out how to give them different process times, however I need to order them very specifically in the queue. For example I want this robot to run: part 1, part 1, part 3, part 3, part 1, part 2, part 2. Is there any way for me to order the process in this way?

This is on Windows 10. When I attempt to download and install the latest version, I am told that I already have version 6.00.00 installed. This is not the case. I have never used this software before. When it then proceeds to ask me to remove the existing version in order to install the new one, it is unable to do so. The installer can only remove installed items, and because the old version was never actually downloaded, it is unable to do so. All attempts to install get stuck in this loop, including deleting the entire install package and redownloading. Anyone got any ideas of what might be going on?

Hi guys.

I found this project siml.ai on X. As a physics student, I use mostly my MacBook and my iPad, and I need to run simulations for classes and research. They say it’s web-based, so it’s nice for me because I don’t have any powerful GPU and I don’t have much time for setting up cloud computing like AWS. Although I would like to learn more about how it works and if it really works and it’s not just another AI buzz crap. What exactly is this NVIDIA Modulus and if it’s web-based, do they use some cloud computing? If yes and I don’t need to setup any AWS, then it’s nice for me as a user. But still there is a question if it’s really useful in terms of reliable results. I don't know much about this NVIDIA Modulus. I have seen some people in the industry, but also at our university, mostly engineers, use Siemens solvers (Siemens STAR-CCM+), and it has pretty useful and reliable results. Have you tried this siml.ai? I thought about trying the free trial.

Anyone wants to help me build a model in SIMIO or knows someone who can help me? TIA

Hey guys, I'm trying to build a Material flow model of a packing shopfloor. I'm doing this in SIMIO software. I want someone to help me build the model . Please help. It's urgent and as part of a bigger project. My intention is throughput analysis. TIA

I have used Arena extensively and am currently learning Simio. I wanted to know how to batch in Simio.

For ex. If I take a manufacturing process where 10 pieces are loaded in a basket and is dipped in paint, in arena I will use the batch module with a temporary batch of 10 and process it.

In Simio, I have the combiner option, but it requires 2 inputs a parent and a member. How can I have just 1 input which batches 10 pieces. I tried connecting the output from the previous server to both the inputs of the combiner, but that is not the right way to model it.

Hi,

In the model that I am working on I am using a server followed by a conveyor (a conveyor that in real life acts as a buffer).

The conveyor has a maximum space to allocate 3 enitities and I do not want any additional entitiy to wait at the output buffer of the server, that is why I set the output buffer to 0.

The issue that I am having is that the part entering the conveyor either stops monentarily at the output buffer of the server (if set at >0) or it blocks the server if set the output buffer at 0. (please note that the entity alignment is set to "Any location")

This does not happen if I substitute the conveyor with a connector or a path. When I use a conveyor the entity does not enter the conveyor right away but it takes some time instead. This time increases as I decrease the travel speed in the conveyor.

As a result I get a server that is blocked a percentage of the time when it shouldnt. This happens even when I set the travel capaciy to infinity and there is no other server blocking downstream of the conveyor, so it is not a matter of capacity of the conveyor or downstream blockages.

I looked up all the settings but I do not find what can be causing this. This happens when I place a conveyor after a server, whan using path or connector the enitity enters the connector / path without any delay.

Does anyone know why this is happening? Thank you!

This is how it looks with output buffer:

The entity is at the output buffer and at the conveyor (it is the same entity, for a moment it is like divided in two, traveling in the conveyor and waiting in the output buffer at the same time.

This is how it looks without output buffer:

The entity that has finished the delay time in the server starts traveling in the conveyor, but at the same time stays blocking the server for some amount of time
