The company I work for has switched to KiCAD and Freecad coz the tools are so damn good. Plus side, Another workbench to learn. Yay.

[@brucewilliams6292]

Now we need to share what you have learned or where you found your info. ;)

[@SomeTechGuy666]

Love the videos. Thanks

[@nickvolling518]

Thank you for sharing.

300° K, not a problem for us Celcius people. Just subtract 273 = 27° C.

[@edsonbrusque]

Yep. We can do K °C convertion in our heads. Sorry you Fahrenheit people out there... :P
Thank you Joko. Excelent video.

[@qzorn4440]

this would be great for electronic heat sinks... thanks a lot...:)

[@dinodano7859]

Hi! Great video, really helped me for what i needed. New to the channel and i am not sure if i missed this out during the video but, why was the result of the transient thermal analysis at 35 sec instead of 30 and 40? Thank you :-)

[@thotbuilds1466]

Could thermal comfort inside buildings be done using OF workbench ? Also could cfd analysis, particularly, wind around buildings for calculating wind loads and wind inside buildings, for natural ventilation be done in freecad + open foam workbench ?

[@poulmack]

Hello,
Great tutorial. Is it possible to get the total heat flux of one face?

[@pierreboyer9277]

How would you do thermal analysis without expansion? Would it get rid of the need of the mesh? Because I'm not interested in the mechanical expansion and my part is very complex which gives a lot of meshes which makes it impossible to compute.

[@mathewmathew08]

Can the FreeCAD do elastomeric deformation?

[@dougbriggs6797]

It's worth noting that if your 'Edit', 'Preferences', 'Units' is set for anything other than 'Standard' or 'MKS' then you won't have values in W/m^2/k available. Units are kg/(s^3*K) is used in all the other Unit systems that I checked. I wasn't able to find a conversion from a quick Google search so I am guessing the value depends how the flux is specified in your material properties. YMMV
I am running 0.19 and running 'Metric Small parts & CNC' and the selection was different and couldn't figure out why for a while. Hope this helps clear up any confusion (like mine).

[@pegefounder]

Why other? Who would use fantasy units from “Lord of the ring” like inch and pounds?

[@dougbriggs6797]

@@pegefounder So you either didn't read or didn't understand my post. Cool.

[@PaulM1984]

Is it possible to implement temperature resistance for different materials, force cooling and model heatsinks?

[@JokoEngineeringhelp]

I have not tried a multi-material analysis for something like that, I'll see what I can find

[@sritech20]

Same question for me to do heat spreader application using graphene and SiO2

[@SV001R]

Mechanical analysis, Thermal analysis... Then the next one would be CFD!

[@OERYV]

Stuck at "Write .inp file" with error "FEM: no mesh object found in analysis. The prerequisite check will fail."
What's the solution for it?

[@gittawat6986]

Hey. Can you make a video about assembly part on free cad.not sure if you already have a video about it covered. I was migrating my project form solid works to work on freecad instead because I didn't use windows anymore.

[@gwyllymsuter4551]

Windows.. It's just hard work. Gone to Linux or OS X?

[@JokoEngineeringhelp]

Sure, I'll throw an assembly video in the pipeline

[@evidennt]

Finally

[@JokoEngineeringhelp]

The price is right.

[@SatishRai1310]

Hi can you make a video tutorial on how to check fem analysis of a valve with air flowvelocity section and also a frequency analysis in fem

[@JokoEngineeringhelp]

I have content uploaded on computational flow dynamics, and all my FEM videos are more or less my collective knowledge of FEM.

[@SatishRai1310]

@@JokoEngineeringhelp thanks for your reply what I want is basically analysis of a one way valve which opens when air flows through the pipe so at what air flow will the valve open will cfd analysis or fem will be useful I am not from engineering background so don't know which analysis to do

[@grougrouhh1727]

why doesnt the temperature gradient between the two side show up?

[@JokoEngineeringhelp]

It's been a long time since I have done this so I could be way off but if I remember it's because the material is highly conductive.

[@NatFablife]

Great content. I know you'd like mine also

[@hardwareful]

The start of the video isn't great - it pretends to give a quick summary what to expect and what to learn, but then only gives you the "Thermal Analysis" keyword to immediately fall off a cliff into details.
* Describe the problem (with pictures and spoken words)
* summarize the approach
* Show a representative set of views of the result.
THEN go into detail, perhaps with a preface regarding the structure of the video, and put timestamps in the description to forward to particular topics like
0:00 half-baked introduction
0:06 Building The Geometry
1:38 Creating an Analysis
- 2:00 Meshing
- 3:22 Adding Constraints
and so on and so forth.
