My bad!

Okay, after a thorough check, there is nothing wrong with my thermal model after all.

As in, I didn't made any mistake in building it, hence it could run without problem. High quality mesh, correct power inputs and all that.

The simulation results showing unbelievably high temperature all round are in fact, the correct prediction, the computational fluid dynamics software doing its job flawlessly.

All the grieves came from me making a rookie mistake: leaving the cabinet in its default settings of adiabatic walls. Meaning I am putting a device that keeps generating heat inside an enclosure that cannot transfer the heat out, so everything within the enclosure keeps getting hotter.

Such a noob mistake! >_<

Funny thing is I don't remember why I changed the settings back to default, because in the previous version, I had it set correctly. It's supposed to be a temporary thing, but thanks to my goldfish memory, I forgot to change it back.

Oh well. My bad, I freely admit it.

At least the grieves were my own making, not from the others.

Goodness knows I have had enough grieves from the others for this particular project.

Of course

Finally completed the thermal model for the major change last week, but of course it cannot run properly.

Some unknown error when reading view factor, can calculate the view factor just fine but when trying to read/write to local hard drive, it just errored out.

Looked up the internet for solution and recommendation. Tried whatever I could but still no dice.

Changed to another radiation model that's more computing resource intensive and suddenly the model has no problem running...

WTF is going on? I have been using the other radiation model for ages, as recent as the previous version of the model last week and it had no problem.

I have no time to debug that, and probably is something beyond my capability anyway, so all I can do now is to use the more computing resource intensive radiation model.

The simulation ran overnight is completed, residuals are good, no divergence and all that. But the temperature is unreasonable high all round. Of course, things cannot just go well for me.

The first thing I checked is the power input. I triple checked and don't see anything wrong with the input. I post-processed the solved case and don't see anything strange with the flow field.

So WTF is wrong with the model? Spent the whole day debugging, and not really getting anywhere.

While I am still cracking my head on this, the team lead informed us there is another major change, the system dimensions are totally different now.

Of course.

Burning out

This is the fourth consecutive weekend that I am working overtime.

Made infinitely worse as this was supposed to be the weekend that I properly rest, a desperately needed break from work.

I got my annual leaves aligned with my manager in the beginning of the month, half day on the past Friday, and full day on coming Monday, to get myself a 3.5 days long weekend to rest and relax. Absolutely no work.

But on past Friday morning, I had to postpone the leaves by a week, because I knew I had to work overtime this weekend. No thank you to take leave just to be working overtime.

No need to add insult to injury.

So I am dead tired, and extremely fed up.

Soon, there will be nothing left to burn.

Low batt

Low energy level. Everyday.

Headache comes and goes. Ever present.

Working everyday, no day off. No break.

Tired. Just tired.

罪加一等

无薪加时工作，是很对不起自己的事，是很贱的罪过。

在公众假期无薪加时工作，罪加一等！

是，我贱、我罪过。

更多的是，我非常十分无奈。

随兴随想 |系列|

有感而发：贱

连续九天的加时工作，除了吃饭、如厕、和难免的载送做司机任务外，真的就是那睁眼就工作到晚上或凌晨闭眼睡觉的那种。

哦，还有那些要找工作间隙，像人体工程学软件促使的工间休息时间，来完成的家务。因为如情人老婆仔所说的那样，要抱着当作放假在家很有空的大儿子没有在心态。

问题是，这“没有在”的人，我还得照顾他的三餐，洗、晒、收他的衣服… 如果真的是没有在我反而轻松些。

欸，不是要写关于那话题，让我言归正传。

连续九天夙兴夜寐的加时工作，既是周末也一样，来赶出热流模拟的数据。

然后就被一句 “热流模拟数据不对” 给敷衍带过。

勾叉零蛋三角形！你敷衍我，我还不是很在意，因为那是你人品的问题，与我无关；但你说我的热流模拟不对，我就非常的在意，那是对我工作品质的攻击！

请把话说好来，热流模拟数据没有问题，数据显示那设计很有问题我们两位散热工程师一点都不出奇，毕竟我们早已跟你们说过了，你们那设计对散热非常不友好。

你们不相信我们散热工程师说的，硬要数据来支撑我们的意见，现在数据出来了，你就讲这样的屁话？

你过后说设计变了，不是热流模型那设计了。那不是我的热流模拟不对，是你改了原本那烂设计又没有告诉团队，却要抛锅到我头上，勾叉零蛋四角形！于是我把你之前发出来给我做热流模型的 3D图，那你说我模拟数据不对的部分的截图，放在团队的即时通讯群里留个证据。

要攻击我的工作品质，请慎重考虑，那是我必会捍卫的事。

会议里跟你要最新的 3D图来修改或重建我的热流模型，你就推说待会。到了下班时间都没有发给我 3D图。第二天星期六我又加时工作来跟你要 3D图，你依旧说待会。我到了中午就下班了，没理由因为那迟迟都发不出来的 3D图傻傻的等，浪费我的周末。

所以这周末我不算真的有加班到，但因为连续那么多天没日没夜的忙，周末没有在做工我竟然有点不习惯，有点莫名的愧疚感。真是的，工作上遇到贱人也就罢了，为什么自己要这么命贱？

Stressed

Worked overtime every single day, including two weekends, for the simulation results shared to team today.

Before the simulation results are available, the thermal team (all two of us) already knew that the thermal performance is going to be bad, but the rest of the team would not listen, and would not make changes to improve the design.

So I had to go through the motion of building the thermal model for this badly designed system, ran the simulations, and showed the results to the team.

The bad results are no surprise to the thermal team, if only the rest of the team could have believed us, we would have made better and more efficient progress in system design.

But alas, such is the team, so such is the progress. Waste of my time and effort really, could have been put to better use.

Still the lead is not fully on board, still pushing back on improvement ideas, rejecting some without a thought.

Great, more rounds of this low value simulation just to have the data for "I told you so".

Rather not really, but oh well, such is the team...

Needless stress.
